Fix usage of CRTSCTS define from termios.h

Browse Source 
NuttX had the CRTSCTS define incorrectly set for only output flow control, which broke our flow control logic. This commit patches NuttX and puts in addition a guard in place to prevent any future issue with the non-POSIX define being incorrect.

This has been debugged and identified by @ecmnet, which was the main contribution for this patch.
