OpenBSD: Remove now obsolete unveil code 

Previous tls_default_ca_cert_file(3) hoisting makes this possible: all
TLS related files are fully loaded into memory by ircConfig() such that
ircConnect() will not do any file I/O.

Call ircConfig() before pledge(2) in the `-o' "print cert" case so this
works out -- that order should have been preserved in the previous
a989e15 "OpenBSD: hoist -o/printCert code to simplify" but fixing it now
nicely demonstrates the achivement even more so.
