Convert files to unix line ends in the repo

These files were aded with windows line ends before we did set the text=auto
attribute for all files in .gitattributes, and this caused phantom changes on
linux workspaces after .gitattributes was introduced.
Now these files appear with linux line ends on linux workspaces and with
windows line ends on windows workspaces, like all source files.
