net-mgmt/nstat: use recommended scheme for unversioned software

The nstat is unlikely to have a version in foreseeable future. Bump
PORTEPOCH and use what the Porters Handbook suggest. Remove the extra
patch, which in reality is just the top commit of the upstream git tree.

Take over maintainership due to maintainer timeout(s).
