lightningd: fix listconfigs rpc-file-mode

It literally contained \" to avoid it being interpreted as a literal;
now we have OPT_SHOWINT we no longer need this hack.

It's obscure, so I'm not bothering with a deprecation cycle.

Changelog-Fixed: JSON-RPC: `listconfigs` `rpc-file-mode` no longer has gratuitous quotes (e.g. "0600" not "\"0600\"").
