Fix kexec forbidding kernels signed with keys in the secondary keyring to boot
commit ea93102f32244e3f45c8b26260be77ed0cc1d16c upstream.
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().
Fixes: d3bfe84129f6 ("certs: Add a secondary system keyring that can be added to dynamically")
