binutils: add support for eBPF

Browse source 
This patch adds support for ELF64 eBPF to readelf, and fixes a `nm'
test to run properly in bpf-*-* targets.

binutils/ChangeLog:

2019-05-23  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* readelf.c: Include elf/bpf.h.
	(guess_is_rela): Hanle EM_BPF.
	(dump_relocations): Likewise.
	(is_32bit_abs_reloc): Likewise.
	* testsuite/binutils-all/nm.exp: Add bpf-*-* to the list of
	ELF targets.
