Only read EC2 regions_exclude list if necessary (#18720)

When specifying a literal whitelist of AWS EC2 regions in the dynamic
inventory configuration file, it should not be necessary to also include
a literal blacklist, especially as the blacklist is not honored in this
case anyway. By reading the literal blacklist only when necessary, it is
possible for a user to provide a more minimal EC2 configuration file.
