check_ircd: OpenBSD pledge(2)

Implement OpenBSD's pledge(2) for the check_ircd.pl Perl script. Since
this is a Perl script, OpenBSD::Pledge(3p) is called within an OS check.

https://man.openbsd.org/OpenBSD%3A%3APledge.3p

I have verified the code both on a current OpenBSD as well as on a
Linux, where it is skipped and does not result in an error.
