Along with the version number, "bpftool version" displays a list of features that were selected at compilation time for bpftool. It would be useful to indicate in that list whether a binary is a bootstrap version of bpftool. Given that an increasing number of components rely on bootstrap versions for generating skeletons, this could help understand what a binary is capable of if it has been copied outside of the usual "bootstrap" directory. To detect a bootstrap version, we simply rely on the absence of implementation for the do_prog() function. To do this, we must move the (unchanged) list of commands before do_version(), which in turn requires renaming this "cmds" array to avoid shadowing it with the "cmds" argument in cmd_select().
