[Cogl] [PATCH] kms: Fix the version check for GBM

[Neil Roberts]

The check for whether to use ‘stride’ instead of ‘pitch’ from the GBM
API tries to check whether the GBM version is >= 8.1.0. However it was
comparing the major and micro components independently so any version
with the minor part set to 0 would fail. The GBM version in Mesa
master is now 9.0.0 which breaks it. This patch changes it to check
the version using the COGL_VERSION_ENCODE macro instead.
