Refresh patches, remove keyfinder patch as upstream seems to use the
correct keyfinder-cli path, since:
https://github.com/beetbox/beets/pull/3467/files
Remove the doing nothing `imagemagick` in `buildInputs` and add a patch
that makes `beets` use `magick` from Nix' path. The patch can be
disabled along with the reference to imagemagick if it's set to `null`.
Formatting: use 1 line per input.
Remove the unevaluated externalTestArgs.beets - it was moved to
`all-packages.nix`.
The maintainer has stopped cutting releases[1]. Since the last release,
1.4.9, includes a dependency that is filled with hate speech[2] it's all
the more reason to package the unstable version and eliminate that
requirement.
Moreover a number of fixes, improvements, and features have landed
since.
