[git commit] truncate: use O_WRONLY|O_NONBLOCK

[Mike Frysinger]

commit: http://git.busybox.net/busybox/commit/?id=6a70db85cfc2aba89fc23edf426a47630f497eb8
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

This matches coreutils behavior.  We don't read the fd, and truncation
does not need blocking.
