In order to integrate some bpftool tests into test_progs, define a few specific helpers that allow to execute bpftool commands, while possibly retrieving the command output. Those helpers most notably set the path to the bpftool binary under test. This version checks different possible paths relative to the directories where the different test_progs runners are executed, as we want to make sure not to accidentally use a bootstrap version of the binary.
