Remove 'gstreamer' variable from purple-3.pc.in

Since ee3bd4532a33 configure.ac no longer sets GSTREAMER_VER because
GStreamer 1.0 is now the only version libpurple supports.
For information on writing a plugin for Purple, Pidgin or Finch, go

HOWTOs in the "Related Pages" section.
You can also generate this documentation locally by passing
