SITL: changed posix_default to posix_sitl

The SITL build is now the default posix build.

The linker script for posix was moved to makefiles/posix.
The rc.S file was moved to posix-configs/SITL/init/
The POSIXTEST board definition is now SITL

To run the SITL test run:

make sitlrun

This replaces the make posixrun target.

The build directory is now Build/posix_sitl.build/
