Create initial /etc/advligorts/systemd_env file during install
The systemd scripts for awgtpman, etc. do not use /etc/advligo/env but instead use /etc/advligo/systemd_env (and perhaps /etc/advligo/systemd_env_hostname ). Because of this, awgtpman will not run after a initial advligorts-cymac install - see TST log 14366.
The installer should create an initial /etc/advligorts/systemd_env with just SITE and IFO in it
