include/stdlib.h: define system()'s prototype for the flat build

Browse source 
The `$(APPDIR)` folder is added to the `$(KERNDEPDIRS)` when
`CONFIG_BUILD_KERNEL=y`. The `depend` phase iterates over the
`$(KERNDEPDIRS)` folders and executes the `depend` recipe of these
folders (including the apps' recipes) with the `__KERNEL__` macro
defined, which prevents `system()`'s prototype from being declared.
