[PATCH] ping: try SOCK_DGRAM if no root privileges

[Cathey, Jim]

Oh, and it helps to know that users on this particular system
do not get access to shells.  Or rather, the account shell _is_ our
custom application.  Bash (or ash) is there, but not exposed.
It's used by admin scripts, booting, etc.

Doesn't really do you much good since BB is still doing
its own name checks.

No, it's not perfect.  Making this kind of relay program a real part
of BB, as a user-selectable option probably, would be best.

And no writable storage anywhere (E.G. a tmpfs for /tmp or similar)
where you can add a handy symlink to the wrapper?
