[Buildroot] [PATCH] package/systemd: create /etc/resolv.conf only if resolvd is selected

[unixmania at gmail.com]

From: Carlos Santos <unixmania at gmail.com>

Or else it becomes a dangling link to /run/systemd/resolve/resolv.conf,
which is never created. Even worst, it also prevents NewtorkManager from
updating resolv.conf.
