[gnrc_icmpv6_error] Fixed multicast detection
...
before this commit the src address was checked for multicast, but the dst address should be checked. Therefore udp multicast packets would be flooded back to the src as ICMPv6 error, as not all nodes had a UDP receiver registered.

gnrc_icmpv6_error: check IPv6 header before starting to build
...
Check for:
- if it exists (critical error condition -- non-IPv6 headers should
not trigger these functions) => assert
- if it has a multicast source (that shouldn't really happen but
people might try weird stuff ;-)
- if it has an unspecified source (can't determine receiver of error
message => don't send it, don't build it)

The stack might still wants to do something with the packet after
copying it to the error message.
