chromium needs to unveil dns files

After upgrading my snapshot yesterday, chromium and ungoogled-chromium
stopped working, throwing ERR_NAME_NOT_RESOLVED on every site.

Turns out it's a case of "rolling its own DNS and wanting to open
resolv.conf", cf. https://marc.info/?l=openbsd-ports&m=177389567528083.
So I've added

/etc/resolv.conf r
/etc/hosts r
/etc/services r
/etc/protocols r

to unveil.main and that seems to fix things. Should these also be in
the other unveil files?

Thanks to Bryan and Claudio for the quick pointers.
