objdump, as: add callx support for BPF CPU v1

Browse Source 
Albeit not being a currently valid BPF instruction, callx is generated
by both clang and GCC when BPF programs are compiled unoptimized.
Until now, GCC would emit it only whe using the experimental
compiler-testing cpu version xbpf, whereas clang would emit it from
v1.  This patch makes GAS to accept callx also starting with cpu v1.

opcodes/ChangeLog

	* bpf-opc.c: Move callx into the v1 BPF CPU variant.

gas/ChangeLog

	* testsuite/gas/bpf/indcall-1-pseudoc.d: Do not select xbpf cpu
	version.
	* testsuite/gas/bpf/indcall-1.d: Likewise.
