app-portage/prefix-toolkit (prefix-stack-setup): revbump

We do not want to have CBUILD build deps in prefix-stack, but CHOST
build deps only.  Since EAPI 7 there is BDEPEND, but EAPI 6 and older
have both CBUILD and CHOST build deps in DEPEND.  As most CHOST build
deps also are in RDEPEND anyway, we omit EAPI 6 DEPEND from prefix-stack
by setting EMERGE_DEFAULT_OPTS="--root-deps=rdeps" - ignored for EAPI 7.
