[BUGFIX] Not working properly on self-hosted runner

Browse source 
* remove fixed default auth socket path
* call `ssh-agent` with auth socket path, if not explicitly given,
  to let the system choose the path
* read SSH_AUTH_SOCKET and SSH_AGENT_PID from `ssh-agent` command output
  and add the as variables
