[PATCH 6/6] winegstreamer: Do not pin winegstreamer.dll.

[Zebediah Figura]

It's not clear what atexit handlers glib installs or why they cause problems.
In fact, current glib source, besides including some wrapper API, has only one
call to atexit(), which simply dumps leaked objects. In any case, keeping this
code around does not seem worthwhile when the problem is not fully understood
and may not exist anymore at all.
