Mahmood Ali 51ba244805 drivers/exec: fix DNS resolution in systemd hosts ...

Host with systemd-resolved have `/etc/resolv.conf` is a symlink
to `/run/systemd/resolve/stub-resolv.conf`. By bind-mounting
/etc/resolv.conf only, the exec container DNS resolution fail very badly.

This change fixes DNS resolution by binding /run/systemd/resolve as
well.

Note that this assumes that the systemd resolver (default to 127.0.0.53) is
accessible within the container. This is the case here because exec
containers share the same network namespace by default.

Jobs with custom network dns configurations are not affected, and Nomad
will continue to use the job dns settings rather than host one.
