libbpf-compat: skip failing netif_receive_skb.linked3.o

Trying to load the ELF gives the following error:

    elf_reader_test.go:665: Error during loading: program trace_netif_receive_skb:
    apply CO-RE relocations: apply fixup target_type_id=67->16253:
    invalid immediate 73, expected 67 (fixup: target_type_id=67->16253)

After some cursory digging this doesn't seem to be a bug in the library
but maybe one in either pahole or clang.

See cilium#739
