scripts/sign-file.c: Add support for signing with a raw signature
This patch adds support for signing a kernel module with a raw
detached PKCS#7 signature/message.
The signature is not converted and is simply appended to the module so
it needs to be in the right format. Using openssl, a valid signature can
be generated like this:
$ openssl smime -sign -nocerts -noattr -binary -in <module> -inkey \
<key> -signer <x509> -outform der -out <raw sig>
The resulting raw signature from the above command is (more or less)
identical to the raw signature that sign-file itself can produce like
this:
$ scripts/sign-file -d <hash algo> <key> <x509> <module>
