There are some tests available in the NetBSD test suite, but we don't
currently pass all of those; further investigation will go into that. For
now, just add a basic test as well as a test that copies from /dev/null to a
file.
The /dev/null test confirms that the file gets created if it's empty, then
that it truncates the file if it's non-empty. This matches some usage that
was previously employed in the build and was replaced in r366042 by a
simpler shell construct.
I will also plan on coming back to expand these in due time.

Note: tcsh(1) has a MK_TCSH=no test, so this should be a separate
package, which requires pre-install/post-install scripts, to be
added later.

This allows the following revisions to be reverted:
rev 1.39 src/bin/cp/cp.c
rev 1.26 src/bin/chmod/chmod.c
rev 1.40 src/bin/rm/rm.c
The following revisions can already be reverted, because they were
already covered by WFORMAT=0:
rev 1.8 src/bin/ls/lomac.c
rev 1.63 src/bin/ls/ls.c
rev 1.8 src/bin/ps/lomac.c
rev 1.34 src/bin/rcp/rcp.c
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
