Update file perm check, add file owner check, update regex for pacha/macha ticket users

Tested the file perm/default checks against stock 11.38, 11.40, 11.42, and 11.44 on CentOS 6, although the perms were all taken from the existing check mostly un-modified, the owner check is new.

Added suid perm check for /usr/local/cpanel/bin/sendmail for versions where case 86561 is not resolved.
