Subject: [PATCH] gnu: libdrm: Restore building libdrm_intel by default.

This should fix mediasdk failing to build by not finding libdrm_intel as it
was not built in libdrm after the update to 2.4.117.

* gnu/packages/xdisorg.scm (libdrm)[phases]: Add phase to correct an upstream
typo which disabled building libdrm_intel on supported platforms by default.
