[gentoo-portage-dev] [PATCH] doins: fix D check, add EPREFIX check

[Fabian Groffen]

bin/ebuild-helpers/doins: fix D check, add EPREFIX check

ED = D/EPREFIX, so checking for ED includes EPREFIX, which when this is
absent fails to check for D.  Simply check for D instead, which catches
both the case for D and ED.

Add check for usage of EPREFIX, like for using D with helpers.
