x11-plugins/i8krellm: update EAPI 6 -> 8

Also removes support in the Makefile for gkrellm1. Both the package
description and dependencies indicate a hard requirement for gkrellm2,
and the gkrellm1 support unconditionally calls 'gtk-config' and
'imlib-config', neither of which are declared as dependencies and thus
might not exist.

Closes: https://bugs.gentoo.org/742953
