Subject: [PATCH] sysctl.d/50-default.conf: allow everybody to create
 IPPROTO_ICMP sockets (bsc#1174504)

This will allows us to remove capability bits from `/usr/bin/ping` and
`/usr/sbin/pfing`. Furthermore other programs like `traceroute -I` start
working for regular users.

The ping_group_range allows to further limit the group IDs that are
allowed to use these sockets. It is difficult to find a sensible
limitation on a generic level, however. Daemons might just as well want
to send out pings as interactive users. Therefore all groups are allowed
by this configuration change.

The maximum group ID seems to be (2**31)-1, contrary to what a suggested
documentation snippet says, that never made into upstream [1].
