mesa: build dri for arm

The isAarch64 applies only to 64bit arm. The commit
e7a2c65 missed support for 32bit arm.

This also removes kmsro as it is not used by Mesa meson.build file. The
kmsro is detected from other galium drivers. This might not be correct
and there probably should be a way to enable this in the upstream but
for now this does nothing.
