netd: load modules for well-known ports

When inheriting well-known ports from systemd (or similar),
we can auto-load the proper *D.pm file based on the port number
without requiring command-line args.

load_mod also gets fixed to use its argument, instead of implicit
$1 since that won't work for our well-known.
