Like we just did for pulling out the errno & signal maps, pull out the
open flag map into a dedicated common file.  All newlib ports are using
the same map which makes it easy.

Now that the use of TARGET_xxx defines have been removed, we can move
this to the common logic so we only build it once for multi-targets.

This is used in a few places where it's not needed.  Drop the include
to avoid the build-time generated header file as we move to drop it.
