package.bbclass: Add SHLIB detection support for mingw targets 

Add support to detect dll files as shared objects as well as process
Windows .dll and .exe files to determine the runtime libraries
dependencies.

This implementation is sufficient to detect and map runtime library
dependencies between packages. And does not implement any version naming
conventions that might apply for .dll files (e.g. lib*-x.dll).
