net-irc/ircmap: Fix swathe of QA issues

- Using the perl privlib trick was both wrong, and unneeded, as the
  modules in question are inherently 'private to this package' and
  are not intended for general use by other tools on CPAN.

- Subsequently, this changes to stashing them in /usr/share/ircmap

- Upstreams homepage has moved

- Upstreams existing SRC_URI's were unresolvable

- Added conversion of upstreams tarball from "ircmap.tar.gz" to
  "ircmap-0.99.tar.gz". Upstream don't actually version their
  releases properly it seems, but its been so long since a release
  its hard to imagine there will be more.

- Convert to EAPI7, though its probably incomplete and this probably
  needs some EPREFIX/DEPEND/BDEPEND/BROOT love, but eh.

- Keyworded ~amd64 as it mostly appears to work for me, but no way
  to test functionality.

- --straight-to-stable'd simply because these are all QA fixups, and
  no point waiting a month to silence the warnings.
