Allow same module name in multiple applications if explicitely excluded

Earlier, reltool expected all module names detected under the lib
directories to have unique names. If this was not the case, the result
was undefined - i.e. the beam file of the duplicated module might be
included in multiple applications in the target area, or it might even
be excluded from all applications.

This commit adds awareness in reltool that a module might occur in
multiple applications, and it is allowed as long as the module or it's
application is explicitely excluded in all but one of the containing
applications.
