gnu: clementine: Fix creating initial database.

It seems a recent version of sqlite broke Clementine's first startup. It turns
out we can patch clementine to fix the problem instead of providing a different
sqlite package:
<https://github.com/clementine-player/Clementine/pull/5669>

* gnu/packages/databases.scm (sqlite-with-fts3): Remove.
* gnu/packages/music.scm (clementine)[inputs]: Replace sqlite-with-fts3 with
sqlite.
[source]: Add clementine-fix-sqlite.patch.
* gnu/packages/patches/clementine-fix-sqlite.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
