Rusty Russell f68c9fa9c9 opt: make sure early cmdline options override config file.
I noticed that --network=regtest didn't override 'network=bitcoin' in
the config file.

Normally we parse the config file first, then the commandline (so the cmdline
wins).  But for early options, we do cmdline first so we can find the config
file.  That was fine when the only early option was the location of the
config file, but now it includes plugins and the network setting.

So do a boutique cmdline parse *just* to find the config file, then parse
the config file early options, then the cmdline early options.
