Commit b4ce0d8b39 ("render/egl: accept negative DRM FD to select
software rendering") added an EXT_device_drm check to figure out
whether the user selected a device with a DRM FD or without one.
However, for KMS-only devices, Mesa will never advertise the
selected KMS node:
3f1d40d230/src/egl/main/egldevice.c (L109)
Instead, pass down a parameter to indicate whether a DRM FD was
passed in.
