native.bbclass: Fix variable remapping coverage

When looking for RDEPENDS to process, bitbake iterates through PACKAGES
*and* PN. Since native.bbclass sets PACKAGES to be empty, its pointless
remapping the list of PACKAGES since this does nothing. There is a problem
since *_${PN} are used by bitbake but not remapped by the native.bbclass
class extension code.

This changes the code to remap _${PN} in both expanded and unexpanded
forms. As a result of this, various surprising dependencies are uncovered
and the patch rectifies those. These are real bugs since they're injecting
unneeded (unremapped) dependencies into the dependency chain.
