The sysentvec sv_imgact_try was used by kern_exec() to allow
non-native ABI to fixup shell path according to ABI root directory.
Since the non-native ABI can now specify its root directory directly
to namei() via pwd_altroot() call this facility is not needed anymore.

For now a non-native ABI (i.e., Linux) uses the kern_alternate_path()
facility to dynamically reroot lookups. First, an attempt is made to
lookup the file in /compat/linux/original-path. If that fails, the
lookup is done in /original-path. Thats requires a bit of code in
every ABI syscall implementation where path name translation is needed.
Also our kern_alternate_path() does not properly lookups absolute symlinks
in second attempt, i.e., does not append /compat/linux part to the resolved
link.
The change is intended to avoid this by specifiyng the ABI root directory
for namei(), using one call to pwd_altroot() during exec-time into the ABI.
In that case namei() will dynamically reroot lookups as mentioned above.

We don't keep comc_port around anymore if the console's not present, but
some things might still try to set one of the environment variables we
hook. In particular, one need not even set efi_com_port/efi_com_speed
in loader.conf; loader may do it itself and induce the crash if ConOut

Perhaps, this does not makes much sense as destroyng %rcx declared by
the x86_64 Linux syscall ABI. However,:
a) if we get a signal while we are in the kernel, we should restore
tf_rcx when preparing machine context for signal handlers.
b) the Linux world is strange, someone can depend on %rcx value
after syscall, something like go.

This change creates a static inline function, BN_check_prime, for
pre-3.0 use which is implemented with the previous (1.1) compatible call
under the covers, `BN_is_prime_ex`.
The `nchecks` parameter value is maintained, even though it has no
noticable behavior change, given that the documentation clearly states
that at least 64 or 128 rounds are executed on the backend, depending on
how many bits there are in the given number being factored out.
