[Buildroot] [git commit branch/2018.11.x] package/s6-networking: fix dependency when libressl is enabled

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=52800efe23e2031ba1b97a180e3a99b194cc8ee8
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.11.x

Commit "c5b85231fb s6-networking: enable SSL if libressl is selected"
actually dropped the dependency on s6-dns and s6 when libressl is
enabled.
Fix this by using += inside the conditional code.
