kexec, KEYS: make the code in bzImage64_verify_sig generic
commit 278311e417be ("kexec, KEYS: Make use of platform keyring for signature verify") adds platform keyring support on x86 kexec but not arm64. The code in bzImage64_verify_sig uses the keys on the .builtin_trusted_keys, .machine, if configured and enabled, .secondary_trusted_keys, also if configured, and .platform keyrings to verify the signed kernel image as PE file.
