audit(4): add tests for several more administrative syscalls
Includes ntp_adjtime, auditctl, acct, auditon, and clock_settime. Includes quotactl, mount, nmount, swapon, and swapoff in failure mode only. Success tests for those syscalls will follow. Also includes reboot(2) in failure mode only. That one can't be tested in success mode. Submitted by: aniketp MFC after: 2 weeks Sponsored by: Google, Inc.
