openssl: prevent warnings from openssl-c_rehash.sh
The openssl-c_rehash.sh script reports duplicate files and files which
don't contain a certificate or CRL by echoing a WARNING to stdout.
This warning gets picked up by the log checker during rootfs and results
in several warnings getting reported to the console during an image build.
To prevent the log from being overrun by warnings related to certificates
change these messages in openssl-c_rehash.sh to be prefixed with NOTE not
WARNING.
