syscalls: REVERTME: clean up warnings when building unit tests

Browse Source 
This is a temporary hack until #5006 is resolved (possibly using

https://github.com/zephyrproject-rtos/zephyr/issues/5006

Unit testing (BOARD == unit_testing) doesn't need the system call
definitions. Because we foward declare with __syscall them as "static
inline" (from common.h), the compilers will complain that the
definition is missing.

Change to only define __syscall as "static inline" if we are not
builing a unit test to avoid said warnings.
