rpc: Pass GPG_TTY and TERM environment variables

Browse Source 
gpg-agent can be used instead of ssh-agent to authenticate
against an SSH server, but in order to do so the GPG_TTY and
TERM environment variables need to be passed through.

For obvious reasons, we avoid doing that when no_tty=1 is found
in the connection URI.
