build: Explicitly depend on gstreamer-tag
Fixes the following on NixOS:
mpris2-provider.c:29:10: fatal error: gst/tag/tag.h: No such file or directory
29 | #include <gst/tag/tag.h>
| ^~~~~~~~~~~~~~~
compilation terminated.
Both gstreamer-base-1.0.pc and gstreamer-tag-1.0.pc has Cflags: -I${includedir}/gstreamer-1.0
,
but they are provided by two different packages in NixOS (gstreamer, gst-plugins-base),
and have different includedir
.
While at it, also clean up references of gstreamer-interfaces and explicitly depend on gstreamer-audio (see commit message).
