[bug#73430] [PATCH] gnu: Add guile-taglib.

[Alec Barreto]

* gnu/packages/guile-xyz.scm (guile-taglib): New variable.

Change-Id: I68cb1945104b64f621c9e6a1689b63f66c59144e
---

This project has neither git tags nor releases, so I just filled in values of 
"0" for version and revision.
Do let me know if there's something else that would be better.

Separately, is there a reason why the =guile= package doesn't have 
"GUILE_EXTENSIONS_PATH" set in its =native-search-paths= field so that it can 
find foreign libs?
The "libtag_c.so" path has to be patched here (and similar patches exist in 
other guile packages).
Shouldn't the "lib" dir of the profile just be added to that guile path, 
rendering all these patches unnecessary?

Best,
Alec
