    libtracker-miners-common: Always call seccomp_release
    
    seccomp_release needs to be called both in case of success and in case of
    failure. As per documentation any seccomp filters already loaded into the kernel
    are not affected.
    
    Closes: https://gitlab.gnome.org/GNOME/tracker-miners/issues/59
