webkitgtk24: fix gstreamer dependency
Fixes:
http://autobuild.buildroot.net/results/a28/a280f23cc29f77ab440edbda05b4e58d6f4856e7/
The .mk file was checking for gst1-plugins-base but then adding
gst1-plugins-good to dependencies.
According to Source/autotools/FindDependencies.m4, the video and web audio
options need the .pc files provided by gst1-plugins-base, so use that.
