stm32: Make default USB_VCP stream go through uos.dupterm for main REPL.

Browse Source 
Use uos.dupterm for REPL configuration of the main USB_VCP(0) stream on
dupterm slot 1, if USB is enabled.  This means dupterm can also be used to
disable the boot REPL port if desired, via uos.dupterm(None, 1).

For efficiency this adds a simple hook to the global uos.dupterm code to
work with streams that are known to be native streams.
