[PATCH] package.bbclass: Add missing PKGR, PKGV, PKGE and ALTERNATIVE variables from PACKAGEVARS

[Richard Purdie <richard.purdie@linuxfoundation.org>]

These variables all take package name extensions and should be considered in sstate
dependency processing.

This may also fix some multilib alternatives issues (unconfirmed).
