samples shell_module: Avoid setting incompatible options

Currently the USB configuration of this sample is selecting POSIX_CLOCK and being built by default with USB_NATIVE_POSIX. This combination is currently not possible due to mutually exclusive dependencies (the host C library) which results in a configuration warning and POSIX_CLOCK being forced to 'n'. Let's instead disable POSIX_CLOCK in this sample USB config overlay, until the USB native driver supports building with embedded C libraries.
