bootmisc: stop deleting /etc/nologin

Baselayout-1.x used to have a DELAYLOGIN option where it would setup
/etc/nologin automatically and then delete it later on.  OpenRC did
not keep that feature, and during the rewrites, ended up just punting
it all the time.  This isn't what we intended, so drop the rm.
