PMS has similar wording for pkg_prerm and pkg_postrm, so (at least
according to the spec) the old package will still be present in
pkg_prerm and will be gone in pkg_postrm.

I don't think that the ebuild can rely on any particular status of the
new package in pkg_*rm (of the old package), or the status of the old
package in pkg_*inst (of the new package).
