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.

Otherwise libsoup is unable to connect through proxies that use default
port (say, 80 for http). Proxy resolver resolves port-less proxy URLs
into network address with zero port, which is passed to connect().
