package/intel-mediadriver: new package

Signed-off-by: Louis-Paul Cordier <lpdev@cordier.org>
[Thomas:
 - add missing Config.in comments
 - fix minor nit in the _LICENSE variable
 - add patch to drop hardening options, especially -fstack-protector,
   which was causing the build to fail on toolchains without SSP
   support]
