bitbake: toaster: fix package data gathering

Under OE-Core, the name under which a package would
be installed in a target may have been different than the
name under it has been built or recorded in the dependencies
listings.

This patch addresses the way that Toaster records package
names, and adds the field of "installed_name" to save the
name under which a package have been installed in an image.
