net-irc/epic5: fix ruby support, bug 650342

Switch to ruby-single.eclass. This fixes bug 650342 but also simplifies
ruby dependency handling. Remove the REQUIRED_USE since this will always
be a blocker for most people and simply build against the currently
selected ruby version provided by ruby-single. This is in effect what
the ebuild was doing before anyway.

Include correct slot for ncurses.

Use EAPI=6.

Closes: https://bugs.gentoo.org/650342
Package-Manager: Portage-2.3.24, Repoman-2.3.6
