Upgrade libsoup to 2.44.2

MMS engine needs a feature (SoupConnection property "local-address")
which appeared in libsoup somewhere between 2.41.5 and 2.41.90.

Requires GLIB 2.36.0 or later. GLIB 2.36.3 is already in git but OBS
configuration needs to be updated to pick it up.
Merge pull request #2 from monich/libsoup-2.44.2

[update] Upgrade libsoup to 2.44.2
