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.

+To create the files for regression testing do the following.
+
+1. Run values.sh for a given architecture and accounting version.
+2. Unpack the generated file and rename acct into VERSION-ARCH.acct.
+3. Run lastcomm -cuseS -f VERSION-ARCH-acct.in |
+   awk '{$4 = ""; print}' >VERSION-ARCH.out.
+4. Compare the reported values in VERSION-ARCH.out against the
+   *.time values found in the file that values.sh generated.
