linaro-vendor-package: Workaround for mesa_prebuilt build issue

The mesa_prebuilt Android.mk's are getting included regardless
of the expected version, which results in the following build
failure:
  build/make/core/base_rules.mk:342: error: vendor/linaro/db845c/20220629/mesa_prebuilt: MODULE.TARGET.SHARED_LIBRARIES.libEGL_mesa already defined by vendor/linaro/db845c/20220303/mesa_prebuilt.
  00:00:47 ckati failed with: exit status 1

So this patch adds some logic to make sure only the expected
version gets added.
