selftest: acct: Add selftest for the acct() syscall 



The acct() system call enables or disables process accounting.
If accounting is turned on, records for each terminating process
are appended to a specified filename as it terminates. An argument of NULL
causes accounting to be turned off.

This patch will add a test for the acct() syscall.
