[PATCH 2/2] 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.

[Yannik Sembritzki <yannik@xxxxxxxxxxxxx>]

Fix this by passing VERIFY_USE_SECONDARY_KEYRING to
verify_pefile_signature().

Backport of ea93102f32244e3f45c8b26260be77ed0cc1d16c
