    linux: Retry VT ioctls while errno == EINTR
    
    When the smart scheduler is enabled, the VT ioctls (particularly
    VT_WAITACTIVE) can be interrupted by the smart scheduler's SIGALRMs.
    Previously, this caused the server to immediately continue on to
    ScreenInit, almost certainly causing a crash or failure because the X
    server that owned the VT hadn't finished cleaning up.  As of commit
    7ee965a300c9eddcc1acacf9414cfe3e589222a8, it causes a FatalError
    instead.
    
    Retrying the ioctl as long as it fails with errno == EINTR fixes the
    problem and allows server regenerations to trigger VT switches that
    actually succeed.
