vyatta-cfg-system: prevent deletion of system based post-hook symlinks

Any system based symlinks installed in the /etc/commit/post-hooks.d
directory were being deleted on either the initial start of the system
or subsequent reboots. This commit resolves this by excluding these
from the deletion process, while still tidying up other non system
symlinks.

This is required for bug #538 (enhancement request) to function as
intended and also enables the Vyatta bug fix 4718 (enhancement), to log
successful commits to syslog with commit type and user name, commited
on February 2012!
