[git commit] ping: revert "try SOCK_DGRAM if no root privileges"

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=f0058b1b1fe9f7e69b415616096fb9347f599426
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

It wasn't working, and fixes on top of it would make ping
noticeably larger.
