Fix kexec forbidding kernels signed with keys in the secondary keyring to boot
The split of .system_keyring into .builtin_trusted_keys and
.secondary_trusted_keys broke kexec, thereby preventing kernels signed by
keys which are now in the secondary keyring from being kexec'd.
Fix this by passing VERIFY_USE_SECONDARY_KEYRING to
verify_pefile_signature().
