pcr/postsrsd: Fix SRS_DOMAIN default value

On systemd systems (ie, Parabola), the default value of the SRS_DOMAIN
configuration variable is "localhost.localdomain", which is different
than both the documented behavior, and the behavior on other init
systems (which is the documented behavior).

So, I've backported a patch from uptream that fixes this issue.
