[OE-core] [PATCH] gst-plugins-good: fix nondeterministic udev dependency

[Andre McCurdy]

Make the v4l PACKAGECONFIG option control building of the video4linux2
plug-in (not use of libv4l, as it did before) and enable by default.
Add a separate libv4l PACKAGECONFIG to control use of libv4l (disabled
by default since libv4l is not part of oe-core).

The default config for gst-plugins-good and gstreamer1.0-plugins-good
is now aligned with regards to v4l, ie:

  v4l support: enabled by default
  v4l use of libgudev: enabled by default
  v4l use of libv4l2: disabled by default

This commit fixes the following build-deps QA Warnings:

  WARNING: QA Issue: gst-plugins-good-video4linux2 rdepends on libudev, but it isn't a build dependency? [build-deps]
  WARNING: QA Issue: gst-plugins-good-video4linux2 rdepends on libgudev, but it isn't a build dependency? [build-deps]
