POSIX arch: Fix C++ main() linkage issue

Browse source 
To be able to define main() in C++ code we need to have its
prototype defined somewhere visibly. Otherwise name mangling
will prevent the linker from finding it.
Zephyr assumes a void main(void) prototype and therefore
this will be the prototype after renaming:
void zephyr_app_main(void);
