[ FAB-6963 ] Fix binary data in log file

From a debug statement in genCRLHandler() from
lib/servergencrl.go, the crl is printed in raw binary.
This change would print the standard string representation
of a []byte stream:

    - log.Debugf("Successfully generated CRL: %s\n", crl)
    + log.Debugf("Successfully generated CRL: %v\n", crl)
