Windows: Don't configure client when not installing client

Windows: Don't configure client when not installing client

The 32-bit tools installer was displaying client configuration wizard
pages.  Since, the 32-bit tools share configuration with the AFS
service, the 32-bit tools installer should not be attempting to change
client configuration.  Remove said wizard pages from the 32-bit tools
installer.
