T3420: Remove service upnp

Remove `service upnp` as it never worked as expected, nft rules do
not integrated and custom patches do not seem like a suitable
solution for now.

Security:
UPnP has been historically associated with security risks due to its automatic
and potentially unauthenticated nature.
UPnP devices might be vulnerable to unauthorized access or exploitation.
