tests: add a test for symbol hiding side effects

The worry here is that a binary linking with libnotmuch might lose
access to Xapian::Error symbols because libnotmuch hides them.

We are careful here to create ./fakedb/.notmuch in order to trigger a
Xapian exception, and not just a missing file check.

Thanks to jrollins and amddragon for suggestions.
