    timerfd_create: accept CLOCK_UPTIME/CLOCK_BOOTTIME
    
    This is a common use case when using timerfd_create to actually use
    it with CLOCK_BOOTTIME on linux which is CLOCK_UPTIME for us.
    
    Note that currently on freebsd CLOCK_BOOTTIME is CLOCK_UPTIME, but the
    semantic is supposed to be different, this has to be fixed later.
    
    Tested with the fnott notification software
