Patch Features module to fix bugs in removing items from a feature

In drutopia_core we're getting superfluous programmatically generated token-related view modes added to the feature. Even if you manually edit the feature to remove the items, they're re-added the next time you generate the feature.

This results from two related bugs in the Features module:

• 'excluded' property not set in *.features.yml
• Regression: "excluded" configuration should not be automatically packaged

Both issues have patches. Until those patches are applied and reach a stable release, we should add them here.
