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 Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
