Subject: [PATCH] guile: require guile-snarf to be available

Even if guile 2.2 is otherwise available, we'd still fail to build if guile
can't find guile-snarf. One example where this happens is on debian,
which has guile-snarf, but not guile-snarf-2.2.

Of course ideally guile-snarf without the '-2.2' would work... but at
least for now let's fix the build-breakage.
