[OE-core] [PATCH] mesa: add PACKAGECONFIG_DISTRO variable for distro specific options

[Simon Busch]

In some cases as distribution just wants to extend the default PACKAGECONFIG instead of
rewriting it completely. Therefor having a PACKAGECONFIG_DISTRO variable which is empty
by default and included in PACKAGECONFIG helps a lot.
