Remove broken net-p2p/p5-Net-DirectConnect-TigerHash
This port has been broken for many months, and the maintainer recommends
that it be removed rather than fixed. He also indicated that
security/p5-Crypt-RHash would be a suitable substitute for this port.
net-p2p/p5-Net-DirectConnect, the only port to use it, has already been
modified to use p5-Crypt-RHash instead
