[FIX] byGlob: Re-included exclude patterns do not add resources to the result set themselves
The current handling of glob exclude patterns may lead to resources being added to a result set even though they do not match the provided glob patterns. This can happen if a negated exclude pattern is provided. Resolves https://github.com/SAP/ui5-builder/issues/367
