[PATCH weston] compositor-drm: Don't use vaapi recorder with unsupported formats

[Ander Conselvan de Oliveira]

From: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira at intel.com>

We only support recording with GBM_FORMAT_XRGB888 format, so don't try
to record if the output has a differnt format.
