ve/net: enable IPPROTO_ICMP inside Containers
iputils-ping 20150815 fails inside containers because socket(PF_INET,
SOCK_DGRAM, IPPROTO_ICMP) is restricted by vz_security_protocol_check()
The patch enables creation of such sockets inside containers.
By default sys_socket still fails because default setting of sysctl
net.ipv4.ping_group_range, however it's enough for iputils-ping 20150815.
Its fallback handles this situation and successfully creates RAW socket.
In mainlune it is enabled in MS kernel v3.13+, see:
commit fd2d5356d902 ("ipv4: Allow unprivileged users to use per net
sysctls")
in future we're going backport this patch and add its save/restore into
criu.
