[Buildroot] [git commit] package/gstreamer1/gst1-plugins-good: add optional support for libv4l

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=4d04534d5aabfec8c5195c9e28c8530323ce7fd7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When libv4l was compiled before, gst1-plugins-good will use it as
optional dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/lib/gstreamer-1.0/libgstvideo4linux2.so | grep NEEDED | sort
[...]
 0x0000000000000001 (NEEDED)             Shared library: [libv4l2.so.0]
