Fixed the gpg-agent plugin for new gpg versions (#6140)

Browse source 
The gpg-agent plugin did not work for gpg versions above or equal to
2.1 because of the `--write-env-file` option deprecation. This new version
works fine and also enables the ssh-agent support only if it is enabled in the
gpg-agent config file.
