[Conf] If CONFFILE path is not available, use the default

If conffile path is not available in envvar, use the default.
We had this feature before and... somehow, this feature
has been removed at some point.
I'm reviving this feature as this makes errors in some systems.

I've added g_assert to avoid similar errors without
detected at the point of failure.
