* gpg-agent: local agent acting as ssh-agent should yield
This happens commonly if someone using home manager with gpg-agent
acting as ssh-agent on both machines.
@rycee brought up how gpg-itself has some support for agents on both
ends, but in that case one is forwarding the gpg-agent socket rather
than forwardning the gpg-agent-as-ssh-agent socket. There is no need to
forward both.
So I think this is a good default:
- Forward just gpg-agent socket and this doesn't matter.
- Forward just the ssh-agent socket and this does the right thing.
- Forward both sockets and now the ssh one takes priority instead, but
forwarding both was always a silly thing to do.
Fix#667
* Update modules/services/gpg-agent.nix

This option enables a GPG Agent restricted socket (aka "extra-socket"), which
can be used to forward GPG Agent over SSH.
Additionally `verbose` option enables verbose output of an `gpg-agent.service`
unit for easier debugging.
