image: Combine image_sig_algo with image_sign_info
Remove the need to explicitly add SHA/RSA pairings. Invalid SHA/RSA
pairings will still fail on verify operations when the hash length is
longer than the key length.
Follow the same naming scheme "checksum,crytpo" without explicitly
defining the string.
Indirectly adds support for "sha1,rsa4096" signing/verification.
