Subject: [PATCH] MODSIGN: do not send garbage to stderr when enabling modules signature

openssl may send garbage to stderr when generating X.509 key pair for
modules signature regardless there was an error or not. It makes more
difficult to create scripts based on kernel error/warning messages.
This patch makes sure openssl logs go to default stdout.
