package/mesa3d: add KMSRO support for vc4

Browse Source 
kmsro allow to support KMS displays with the renderonly layer used to
attach a GPU [1].

Quote from mesa3d meson.build: "kmsro driver requires one or more
renderonly drivers (vc4, etnaviv, freedreno)". But only vc4 support is
available by using the (deprecated) autotools build system [2].

This will also be used by mesa to support KMSRO with the upcomming
Panfrost and Lima Gallium drivers.
