    libtracker-miners-common: Allow 'mbind' syscall in seccomp
    
    This syscall allows setting the NUMA policy for the pages allocated
    in mmap-ed memory. This seems a fair thing to do, given the scary
    features of this syscall are still under CAP_SYS_ADMIN.
    
    This was seen through GStreamer in Ubuntu 22.04
    
    Fixes: https://gitlab.gnome.org/GNOME/tracker-miners/-/issues/210
