I suggest we create a new special -keystore value "<<CACERTS>>" which acts like an alias of the cacerts file. Creating a new option means we have to document its relation with the existing -keystore option. The new name can also work with the -importkeystore command. 

Like this:

keytool -list -keystore <<CACERTS>>

The name is inspired by <<ALL FILES>> in FilePermission. I'm open to other styles.
