Add a unit test for this. I tested the test by introducing the bug

After r337820, which "corrected" some spaces-instead-of-tab whitespace
issues in the libkqueue tests, jmg@ pointed out that these files were
originally space-based, not tab-spaced, and so the correction should
have been to get rid of the tabs that had been introduced in previous
changes, not the spaces. This change does that. This is a whitespace
only change; no functional change is intended.

FreeBSD's mkstemp sets the temporary file's permissions to 600, and has ever
since mkstemp was added in 1987. Coverity's warning is still relevant for
portable programs since OpenGroup does not require that behavior, and POSIX
didn't until 2008. But none of these programs are portable.
umask(2) should always be used prior to mkstemp(3) so the temporary file
won't be created with insecure permissions.

ian@ pointed out that in the test_abstime() function time(NULL) is
used twice; once in an "if" test and again in the enclosed error
message. If the true branch was taken and the process got preempted
before the second time(NULL) call, by the time the error message was
generated enough time could have elapsed that the message could claim
that the event came "too early" but print an event time that was after
the expected timeout. Correct by making the time(NULL) call only once
and using that returned time in both the "if" test and the error
message.

If a timer is updated (re-added) with a different time period
(specified in the .data field of the kevent), the new time period has
no effect; the timer will not expire until the original time has
elapsed. This violates the documented behavior as the kqueue(2) man
page says (in part) "Re-adding an existing event will modify the
parameters of the original event, and not result in a duplicate
entry."
This modification, adapted from a patch submitted by cem@ to PR214987,
fixes the kqueue system to allow updating a timer entry. The
kevent timer behavior is changed to:
* When a timer is re-added, update the timer parameters to and
re-start the timer using the new parameters.
* Allow updating both active and already expired timers.
* When the timer has already expired, dequeue any undelivered events
and clear the count of expirations.
All of these changes address the original PR and also bring the
FreeBSD and macOS kevent timer behaviors into agreement.
A few other changes were made along the way:
* Update the kqueue(2) man page to reflect the new timer behavior.
* Fix man page style issues in kqueue(2) diagnosed by igor.
* Update the timer libkqueue system test to test for the updated
timer behavior.
* Fix the (test) libkqueue common.h file so that it includes
config.h which defines various HAVE_* feature defines, before the
#if tests for such variables in common.h. This enables the use of
the actual err(3) family of functions.
* Fix the usages of the err(3) functions in the tests for incorrect
type of variables. Those were formerly undiagnosed due to the
disablement of the err(3) functions (see previous bullet point).
