v4l2-apps: move libraries around to make the directory tree flatter
From: Hans Verkuil <hverkuil@xs4all.nl>
Instead of having libv4l2util in v4l2-apps/lib and libv4l in v4l2-apps/lib/libv4l,
both are now moved to v4l2-apps/libv4l2util and v4l2-apps/libv4l.
This is much cleaner and less confusing.
Priority: normal
