Remove SyncFB video output plugin, and related documentation and code.

Matthias Dahl, the last maintainer of the code, confirms that the needed Linux kernel module is not building anymore, and thus this is unusable.
Please consider using VIDIX or DirectFB instead, which should both work fine with Matrox cards.
