CVE-2020-25717 selftest: Only set netbios aliases for the ad_member env

The provision_ad_member() function is reused by different
setup_ad_member*() functions. Each environment needs to have unique
netbios aliases as they are all in the same network.
The aliases should only be set for the 'ad_member' environment.
