[racket] DrRacket, OSX, and xattr

Two reasons:

1. DrRacket isn't always the default file association on my mac.
2. Something keeps butchering the xattrs (My guess is dropbox) so DrRacket
keeps prompting me to overwrite the file on save and revert the file on run
(more or less every time I do either). This is recent, but I'm not sure
what changed. The only thing I remember updating recently is DrRacket, but
who knows what is updating in the background.

Either way it seems like xattrs causing overwrite/revert prompts is bad
behavior, regardless if saving new xattrs is correct. It seems a bit like
saying "the file was modified because you added the setuid bit... do you
want to overwrite or revert?". The file wasn't modified, the file system
metadata was.
