Subject: [PATCH] Link directly against libnotify

Dynamically loading the library isn't ideal since the soname
can change silently on us.  Additionally, notify-send is
shipped as part of libnotify, so we aren't actually bringing
in a new dependency.  Since we'd need to patch the source and
rebuild for new sonames anyway, there's little benefit to
dynamically loading libnotify.

Plus, this has the benefit of cleaning up the code, as well as
ensuring we'll catch any future soname changes sooner.
