Subject: tools: bpftool: add bash completion for CFG dump
Patch-mainline: v4.17-rc1
Git-commit: d96fc832bcb6269d96e33d506f33033d7ed08598
References: bsc#1109837

Add bash completion for the "visual" keyword used for dumping the CFG of
eBPF programs with bpftool. Make sure we only complete with this keyword
when we dump "xlated" (and not "jited") instructions.
