stdio: Disable USE_XPRINTF envar.

Browse source 
As xprintf has not kept up with our standard printf(3) implementation,
it is becoming increasingly dangerous to continue to allow it to take
over if USE_XPRINTF is defined.  Remove that code, while still allowing
applications which know about xprintf to select it.
