Don't define same logging category in both plugins

Both ffmpeg and gstreamer plugins define the same logging category,
which breaks application linking when using static linking:

error: /usr/lib/plugins/multimedia/libgstreamermediaplugin.a(qgstreamerimagecapture.cpp.o): multiple definition of 'qLcImageCapture()'
/usr/lib/plugins/multimedia/libffmpegmediaplugin.a(qffmpegimagecapture.cpp.o): previous definition here
