Minimal-printf: Fix wrapping of printf functions for the ARM compiler

As the ARM compiler is in GNU compatible mode, it defines __GNU__ which
(based on pre-processor condition in  mbed_printf_implentation.h)
causes the printf functions to be wrapped using _wrap_* instead of
$Sub$$*.

This commit modifies the pre-processor
conditions to check for __GNUC__last in order to correctly
substitute the printf functions depending on the toolchain in use.

It also gets rid of $Super$$* substitution as it is not needed. $Super$$
is used to identify the original unpatched functions.

Missing substitutions for ARM compiler internal optimized "printfs" are
also added.
