pkg-auto: Import a stripped-down version of eapi7-ver.eclass into impl
The eclass was removed from Gentoo, so we followed suit. This broke the pkg-auto code. Thus I imported the eclass into the impl directory as gentoo_ver.sh, threw away all the unnecessary parts and moved some from pkg_auto_lib.sh to the new file. This allowed me to also drop a hack where I was grepping for the version regexp in the eclass. Now I'm just exporting it.
