crypto/x509: add more detail to the error message arising from a missing hash function. #7735
If a certificate is signed with a hash function that wasn't compiled in the error message isn't bad, but could be better: x509: certificate signed by unknown authority (possibly because of "x509: cannot verify signature: algorithm unimplemented" while trying to verify candidate authority certificate "CA Cert Signing Authority")

@agl would the direct error message
x509: cannot verify signature: algorithm unimplemented
suffice? Catch it right after it has occured.
