.gitattributes: Set platform-specific line-endings
.gitattributes: Set platform-specific line-endings

Shell scripts are Unix-specific, and batch files are Windows-specific.

(Using the wrong line-endings can cause these scripts not to run.)

Setting this in .gitattributes should ensure files are checked out
locally (and published to the npm package registry)
with the correct line-endings.
