bug: service.gpg-agent: SSH_AUTH_SOCK not set

[trev-dev]

Are you following the right branch?

Is there an existing issue for this?

Issue description

It looks like $SSH_AUTH_SOCK is stubbornly stuck at /run/user/1000/keyring/ssh after setting up services.gpg-agent.

gpgconf --list-dirs agent-ssh-socket puts out /run/user/1000/gnupg/S.gpg-agent.ssh

All of my other configs look great. I can't seem to use the gpg-agent to connect however.
