Subject: [PATCH] Fix qbittorrent startup loop on aarch64: drop
 s6-notifyoncheck

s6-notifyoncheck writes to fd 3 when its readiness check passes, but
the LSIO aarch64 image's svc-qbittorrent service has no notification-fd
file so s6-rc never opens fd 3. s6-notifyoncheck exits with EBADF, s6
sees the supervised process die and immediately restarts it, producing
the infinite "Starting qBittorrent..." loop seen on odroid-c2 and other
aarch64 boards.

Drop s6-notifyoncheck entirely and exec qbittorrent-nox directly under
s6-setuidgid so s6 supervises the real process. Silent mode is handled
by redirecting the shell's fds before exec rather than passing a
/dev/stdout path (avoids a separate class of ARM container fd issues).
