musicscanner: Compare music_directory.path as binary

[Ian Campbell <ijc@…>]

SQL string comparisons are case insensitive by default (who knew!), meaning that a music rescan will not pickup a renamed directory if it differs only in the case. Use BINARY rather than arranging for a case-sensitive comparison because the latter still considers 'a' and 'á' equal but for paths we need literal binary sameness. Apply the same logic to music_songs.filename, although I've not tripped over a related issue there.

I have runtime tested this with the fixes/0.28 branch and build tested against master, the tip of both is identical for the file in question so I hope this is acceptable.
