    Add work-around for bug #3167
    
    "UEFI boot hangs right after initializing UEFI framebuffer."
    It actually boots but the system console is not shown.
    
    I had this issue on a TUXEDO InfinityBook Pro 14v4.
    This commits allows me to boot by setting loader tunable
    machdep.hack_efifb_probe_early=1.
    
    This commit is not intended to be there forever.
    It's there for people who experience the same issue and want
    a quick and easy way to test if this fixes their booting issue.
