Quentin Monnet a18094c95d bpftool: Fix bug for long instructions in program CFG dumps
BugLink: https://bugs.launchpad.net/bugs/2025387

[ Upstream commit 67cf52cdb6c8fa6365d29106555dacf95c9fd374 ]

When dumping the control flow graphs for programs using the 16-byte long
load instruction, we need to skip the second part of this instruction
when looking for the next instruction to process. Otherwise, we end up
printing "BUG_ld_00" from the kernel disassembler in the CFG.

Fixes: efcef17a6d ("tools: bpftool: generate .dot graph from CFG information")
