Change asterisk to 'x' in FQDN of SelfSignedCertificate (#11245)

Motivation:

`SelfSignedCertificate` creates a certificate and private key files and store them in a temporary directory. However, if the certificate uses a wildcard hostname that uses asterisk *, e.g. `*.shieldblaze.com`, it'll throw an error because * is not a valid character in the file system.

Modification:
Replace the asterisk with 'x'

Result:
Fixes #11240
