init.rc: allow IPPROTO_ICMP support
Allow userspace programs to create IPPROTO_ICMP sockets.
This socket type allows an unprivileged program to safely
send ICMP_ECHO messages and receive the corresponding
ICMP_ECHOREPLY messages, without relying on raw sockets or
setuid programs.
Please see http://lwn.net/Articles/443051/ for details.
In particular, this allows us to use a version of ping
which doesn't have any capabilities
(https://android-review.googlesource.com/52072).
In addition, this allows us to safely implement an IPv4 ICMP
based version of InetAddress.isReachable()
