Updated elfutils to 0.173, using the fedora 28 packages and, as noted in
https://github.com/cilium/cilium/pull/5106/files ["bpf, doc: further
improvements on the BTF related section #5106"] there is no need to pass
the '-mattr=dwarfris' to llc to have DWARF sections correctly parsed by
tools like pahole.
