Update Unbound to 1.19.0 (fixes existing error with trunk version)

[gaige]

Unbound 1.19.0 fixes a problem that @jperkin reported to the unbound folks (in super detail) about setting IPV6 options mistakenly on an IPv4 socket. I've built locally and tested with the 1.19.0 source against trunk.

If you'd prefer another format for ease of integration (like a pull request of real patch file) let me know.

Thanks for working on this! pkgsrc trunk was already updated with this change in NetBSD@68cf603 but it's appreciated.

The only note to make for future pull requests is that when updating a package version we simply remove any existing PKGREVISION rather than setting it to 0.
