Move part of screenshooter.c to weston-screenshooter.c

Browse source 
This patch splits screensooter.c so that the code implementing
the private screenshooter protocol and launching the client is
moved to a weston specific file, leaving only the code that can
be shared between compositors in screenshooter.c.
Two exported functions are added in screenshooter.c to start and
stop the recorder.
