image.bbclass: use un-renamed packages in RDEPENDS
The issue was that PACKAGE_INSTALL* get debian package renaming applied, but
this renaming is outside of bitbake's knowledge. Making RDEPENDS use
PACKAGE_INSTALL, therefore, caused problems when adding libraries to images
directly rather than indirectly.
While I'm at it, change it to ensure PACKAGE_INSTALL_ATTEMPTONLY packages
also end up in RDEPENDS, not renamed.
