Subject: 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
