kexec_file: split KEXEC_VERIFY_SIG into KEXEC_SIG and KEXEC_SIG_FORCE
This is a preparatory patch for kexec_file_load() lockdown. A locked down
kernel needs to prevent unsigned kernel images to be loaded withs/to be loaded/from being loaded/ (my own mistake :-)) Otherwise looks good. Thanks for improving my idea.
