Fix line endings in etc/curves-mapping.txt

The file etc/curves-mapping.txt currently has CRLF line endings and this seems to cause problems with git since .gitattributes now specifies LF line endings for .txt files. This commit changes the line endings for the file in order to (hopefully) prevent problems with git.
