[PATCH RFC 2/4] package.bbclass: Rewrite sonames data structure to include library path

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

In order to do more advanced processing of the shared libraries, we need
to know where a given library is located on disk so we can know whether
its a system path or a private directory for example.

This patch adds this information into the 'sonames' data structure.
