r312992 removed RESTARTCMD_WITH_ARG for @RESTARTCMD something@ but
reverted the sed to be '@RESTARTCMD \(.*\)@' and RESTARTCMD= to be
the value of RESTARTCMD_WITH_ARG.

openresolv: update to version 3.9.0.
It is now possible to drop the _WITH_ARG vars thanks to a change to the
pdns_recursor upstreamed by Guy Yur.

Certain features, such as resolv_conf_passthrough=NULL, do not work
correctly due to this missing substitution.
Also remove the @PREFIX@ substitution, which is no longer needed.

After r303062, which brought openresolv 3.8.1, we need to replace an
additional @RESTARTCMD@ in resolvconf.
Apply a read fix this time.
