Features exports including Panels stuff (*.pages_default.inc, *.panelizer.inc, etc) use incorrect indentation

The files created by Features that contain exports of Panels stuff have incorrect indentation. This includes, for example, *.pages_default.inc and *.panelizer.inc.

Since we are trying to make coding-style fixes to Panopoly per #2447605: [META] Perform coding style fixes and I'd like to eventually add checks for this to the automated tests on Travis-CI per #2448755: Add check for coding-style to Travis-CI tests, we don't want:

• False positives on all those files (although, maybe there is someway to mark them to be ignored?)
• Having to make manual corrections to those files after every drush fu

If possible this should be fixed at the source, either in Features, Panels or CTools (where ever the extra indent is coming from).
