Kairui Song 278311e417 kexec, KEYS: Make use of platform keyring for signature verify
This patch allows the kexec_file_load syscall to verify the PE signed
kernel image signature based on the preboot keys stored in the .platform
keyring, as fall back, if the signature verification failed due to not
finding the public key in the secondary or builtin keyrings.

This commit adds a VERIFY_USE_PLATFORM_KEYRING similar to previous
VERIFY_USE_SECONDARY_KEYRING indicating that verify_pkcs7_signature
should verify the signature using platform keyring.  Also, decrease
the error message log level when verification failed with -ENOKEY,
so that if called tried multiple time with different keyring it
won't generate extra noises.
