Add tests for utimes(2), futimes(2), lutimes(2), futimesat(2), mprotect(2) and undelete(2)

[aniketp]

Summary

This revision introduces atf-c(3) test cases for verifying the proper auditability of
the aforementioned system calls. The syscalls are in file-attribute-modify audit class

• utimes(2)
• futimes(2)
• lutimes(2)
• futimesat(2)
• mprotect(2)
• undelete(2)

Note: Only the failure mode of undelete(2) has been tested as it works only for whiteout
files in union file-system, which is not used much anymore.

Test Plan

Execute make && make install from test/sys/audit.
Execute kyua test from /usr/tests/sys/audit. All testcases should succeed.

The man page doesn't specify what 0 means as a protection value. You should use PROT_NONE instead.

Use PROT_NONE instead of 0 for mprotect_success
