net-dns/rbldnsd: new version 0.998b.

This new version doesn't offer any new features or bug fixes, since
our 0.998-r2 contains the two important patches from the upstream
v0.998a and v0.998b. However, this release does let us drop those
patches, and brings the Gentoo version in line with the latest
upstream one, preventing some confusion.

In addition, EAPI=7 is now used, and the dependencies have thus been
reorganized. The "rbldns" user now also has its home directory set to
the default (/dev/null) rather than /var/db/rbldnsd. This change is in
preparation for a GLEP 81 user package that will use the default home
directory, and allows us to test the new setting for a bit before
making it permanent.
