security/logcheck: Add patch to change crontab entry

When the host is heavily loaded, the log files can grow incredibly and
one logcheck invocation may not complete before it is invoked next
time.

This commit add patch to change crontab entries so it uses lockf(1) to
avoid multiple invocation of logcheck under such situation as above.
