    libtracker-miners-common: Distcheck fix
    
    Make sched_setattr error out softly (return EPERM, instead of a terminating
    SIGSYS signal), so we can more or less cope with that syscall, added in
    recent glib.
    
    This indirectly relies on https://gitlab.gnome.org/GNOME/glib/issues/2039
    being fixed, and glib not triggering g_error() on that syscall failing.
    Let's double down on EPERM being possibly returned ATM, glib master still
    currently breaks tracker-extract, and it won't cause ill effects on older
    glib.
