make unlockwiki drop the cgilock

This is necessary so that things that fork to the background,
like pinger, and inline ping, don't block other cgis from running.

Note that websetup also calls unlockwiki, before refreshing / rebuilding
the wiki. It makes perfect sense for that not to block other cgis.
