apparmor: Refactor to remove bprm_secureexec hook
The AppArmor bprm_secureexec hook can be merged with the bprm_set_creds hook since it's dealing with the same information, and all of the details are finalized during the first call to the bprm_set_creds hook via prepare_binprm() (subsequent calls due to binfmt_script, etc, are ignored via bprm->called_set_creds). Here, all the comments describe how secureexec is actually calculated during bprm_set_creds, so this actually does it, drops the bprm flag that was being used internally by AppArmor, and drops the bprm_secureexec hook.
