gst_all_1: Fix evaluation on Darwin, fix gstreamer builds.

Commit be382109ad01d0aa8660f2b19a20e345c86d246b broke evaluation
on Darwin because it added these unconditional buildInputs
that don't evaluate on Darwin:

    libnice librdf lilv lv2 serd sord sratom

This commit fixes it, and also fixes recently-added new dependencies
for other packages accordingly.

It further fixes the build of many gstreamer packages on Darwin.
