Complete the usr.bin/yacc kyua integration work I originally
submitted via r268811

- Install the Kyuafile by adding FILES to FILESGROUPS
- Run the testcases with an unprivileged user

Some of the testcases depend upon behavior that's broken when
run as root on FreeBSD because of how permissions are treated
with access(2) vs eaccess(2), open(2), etc

- Simplify the test driver to just inspect the exit code from
run_test because it now exits with 0 if successful and exits
with !0 if unsuccessful
- Don't do ad hoc temporary directory creation/deletion; let Kyua
handle that
- Add entries for files removed in r268811 to
OptionalObsoleteFiles.inc
