This is 'make tinderbox' clean.

Migrate tools/regression/{usr.bin/lastcomm,usr.sbin}/ to the new tests layout.

This change was originally going to only migrate the usr.sbin tests but, as
it turns out, the usr.sbin/sa/ tests require files from usr.bin/lastcomm/
so it's better to just also migrate the latter at the same time. The other
usr.bin tests will be moved separately.

To make these tests work within the test suite, some of them have required
changes to prevent modifying the source directory and instead just rely on
the current directory for file manipulation.

Fix lastcomm tests under amd64.

Force the use of TZ=UTC and adjust data files accordingly. I have no means
to verify that the data files for the other architectures are valid.

You need to be root to run this test.

It is expected these are chmod +x.

Set magic fbsd:nokeywords property that allows files to bypass
keyword expansion. (file-specific replacement for CVSROOT/exclude)

Add sparc64 regression test files.

Modify file generation instructions to remove the tty field:
the mapping from number to name differs between systems,
and will cause tests to fail.
