objtool: Print top level commands on incorrect usage
Print top-level objtool commands, along with the error on incorrect
command line usage. Objtool command line parser exit's with code 129,
for incorrect usage. Convert the cmd_usage() exit code also, to maintain
consistency across objtool.
After the patch:
$ ./objtool -j
Unknown option: -j
usage: objtool COMMAND [ARGS]
Commands:
check Perform stack metadata validation on an object file
orc Generate in-place ORC unwind tables for an object file
$ echo $?
129
