weston: upgrade to 1.3.0

weston: upgrade to 1.3.0

Remove backported patches that are now integrated.

No need to patch build to install examples with --enable-demo-clients, update
FILES now that all examples are being installed.

Remove cairo-gl option as our cairo doesn't support GL (yet), remove
--disable-android-compositor as it was dropped upstream, and add PACKAGECONFIG
for the VAAPI-based recorder as otherwise it's a floating dependency (libva is
in meta-intel).

Based on work by Ewan Le Bideau-Canevet <Ewan.LEBIDEAU-CANEVET@eurogiciel.fr>.
