  1. rustc: Avoid /tmp/ in graphviz writing 

    This issue was reported to [email protected] by Sebastien Marie following
our recent [security advisory][1]. Because `/tmp` is typically globally writable
it's possible for one user to place symlinks in `/tmp` pointing to files in
another user's directories, causing `rustc` to overwrite the contents of
innocent files by accident.

This patch instead defaults the output path here to the cwd which should avoid
this issue.
