bundle.c: don't leak the "args" in the "struct child_process"

Browse source 
Fix a leak that's been here since 7366096de9 (bundle API: change
"flags" to be "extra_index_pack_args", 2021-09-05). If we can't verify
the bundle, we didn't call child_process_clear() to clear the "args".

But rather than adding an additional child_process_clear() call, let's
verify the bundle before we start preparing the process we're going to
spawn. If we fail to verify, we don't need to push anything to the
child_process "args".
