gl: add gstreamer-video to pkg-config path

This is very similar to https://bugzilla.gnome.org/show_bug.cgi?id=765804 except that it is GstGL which will not compile.

I am also running Unbuntu 16.04 and compiling in gst-uninstalled mode.

Build output:
  GEN      GstGL-1.0.gir
Couldn't find include 'GstVideo-1.0.gir' (search path: ['/home/bbcrd/gst/master/gstreamer/gst', '/home/bbcrd/gst/master/gstreamer/libs/gst/base', '/usr/share/ubuntu/gir-1.0', '/usr/share/gnome/gir-1.0', '/usr/local/share/gir-1.0', '/usr/share/gir-1.0', '/var/lib/snapd/desktop/gir-1.0', '/usr/share/gir-1.0', '/usr/share/gir-1.0', '/usr/share/gir-1.0'])

Confirmed that attached patch allows compilation to continue.
