Correct line endings and file permissions

[Eitot]

A few minor changes to a couple of files for consistency. git warns about the CRLF line endings:

$ git diff
warning: CRLF will be replaced by LF in Carthage/Checkouts/FeedKit/Tests/xml/Content.xml.
The file will have its original line endings in your working directory.

Hi, @Eitot. Merging this. Thank you for contributing 😄

Ok, so I closed this by mistake before merging, and for some odd reason, the reopen button is grayed out. I'm guessing maybe it's because the originating repository no longer exists 🤔 So so Sorry! I'll make sure to include theses changes in the next version, none the less.
