[bug#39155] gnu: tuxguitar: Build and install alsa plugin.

* gnu/packages/music.scm (tuxguitar): Allows midi sound output when using
  a synthesizer like timidity.

  [inputs]: Adds alsa-lib as an input.
  [phases]: No longer change build directory context between phases.
  [install]: Now install desktop, mime and manual files.

I've changed the format of this log message a bit so it's less
repetitive.

I left this comment in since it notes that TuxGuitar actually doesn't
have a test suite, and that we haven't just disabled it for another reason.

Hello Kei,

Apologies for removing this comment. I had not thought of this when I
removed it, thanks for reviewing this and merging.
