gnrc_icmpv6_echo: avoid crashing when pktbuf full
...
Once the packet buffer is full on heavy network load, gnrc_netif_hdr_build may return NULL. In that case, the following unchecked access to hdr->data leads to a crash.

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)

gnrc_icmpv6_echo: fix ping for loopback
...
At the moment ping is crashing if one pings the loopback address.
This was caused in #8214 when we moved interfaces from `kernel_pid_t`
ID to pointer-based handling, since loopback doesn't evaluate to such
an interface.
