This is a problem in eglibc, the header <bits/in.h> defines
ICMP6_FILTER to 18 as it should be on kFreeBSD, but to 1 in
<netinet/icmp6.h> which is the one being used by ping6.
Once replaced with the correct code, it does not error out, but it
still does not work, as the ICMP6_FILTER_SETPASS* and
ICMP6_FILTER_SETBLOCK* macros are also wrong, they are inverted,
memsetting 0xff where they should be using 0x0 and setting and
clearing the bits where they should do the reverse.
