Bugzilla 2.18 and on use contrib/sendbugmail.pl, not processmail.

During 2.17, Bugzilla ditched the old 'processmail' script. With 2.18
contrib/sendbugmail.pl arrived in its place.

For notification emails to work properly, sendbugmail.pl requires as
its second parameter the Bugzilla user who made the commit. Otherwise
the user will not be recognised as the committer, and will receive
notification emails about the commit regardless of their preference
about being notified on their own commits. This parameter should be given
to processmail also, but wasn't for historical reasons.

Add new config with the local Bugzilla install directory, and provide
defaults for the notify string which should work for most setups.
Still permit notify string to be specified, and for backwards
compatibility with any extant notify strings try first interpolating
notify string with old-style single bug ID argument. Add new 2.18
support version to introduce sendbugmail.pl.

In other words, this update should be backwards-compatible with existing
installations, but offers simplified setup in most cases. And as a bonus
Bugzilla notification emails will be dispatched correctly; notifiers will
not receive an email unless configured to do so.
