Enable the spandsp plugin

Olivier Crête said that having the spandsp plugin in Fedora's
gstreamer1-plugins-bad-free would enable running the farstream02 unit
tests. This seems like a worthwhile goal to pursue.

However, this does introduce a new dependency on the spandsp package,
and since it's only being enabled to make upstream development easier,
it's better to keep it in the -extras sub-package for the time being.
