mb/lenovo/s230u: Fix USBDEBUG check

- Change preprocessor #if to standard C if.  This will get optimized
out if the config option is disabled, but lets the compiler check the
contents.
- CONFIG_USBDEBUG is always going to be defined even if it's disabled,
so this check is not going to work as expected.
See the coreboot Kconfig documentation in /Documentation/core/Kconfig.md
