    htl: Fix sigset of main thread

    d482ebfa6785 ('htl: Keep thread signals blocked during its initialization')
    fixed not letting signals get delivered too early during thread creation,
    but it also affected the main thread, thus making it block signals by
    default.  We need to just let the main thread sigset as it is.
