Consolidate determination of UID/GID to run as

Currently the logic to work out what UID and GID we will run as is spread
across conf().  If --runas is specified it's handled in conf_runas(),
otherwise it's handled by check_root(), which depends on initialization of
the uid and gid variables by either conf() itself or conf_runas().

Make this clearer by putting all the UID and GID logic into a single
conf_ugid() function.
