Log Message:
Take apache22 out of PKG_APACHE_ACCEPTED, because this conflicts with
apache22 >= 2.2.10, and we're now on 2.2.21.

Ideally this would instead accept apache22 older than 2.2.10, but
given how old (and insecure) that is there's not much point. I guess
if anyone really really wants to do that they can revert this change
locally... but I can't say I recommend it.
