[PATCH 1/5] xfree86: always enable SIGIO on OsVendorInit (#50957)

Drivers call xf86InstallSIGIOHandler() for their fd on DEVICE_ON. That
function does not actually enable the signal if it was blocked to begin
with. As a result, if one vt-switches away from the server (SIGIO is
blocked) and then triggers a server regeneration, the signal remains
blocked and input devices are dead.
Avoid this by always unblocking SIGIO when we start the server.
