Subject: [PATCH xserver] mustard: Work around broken fbdev headers

This configure check is somewhat pointless as we have our own copy of
the fbdev ioctl declarations. There's also a bug in the version of the
kernel headers I happen to want to build against, where an IS_ENABLED()
escaped into uapi like it oughtn't.

Nerf the test so we build the right fbdevhw code.
