libxl: fix gfx_passthrough config option (including dropped hunk)

Add the missing hunk from 22711:4f6fee3a456e (fixed up for intervening
movement of dm info) to actually pass the -gfx_passthru argument to
qemu.

Also change the idl comment for the gfx_passthrough config setting to
that from Sergey.
