runtime: return 0 from C function in test

Browse Source 
This function's prototype includes a return value, so return a value.
Otherwise clang gets upset:

    --- FAIL: TestDLLPreloadMitigation (1.40s)
        syscall_windows_test.go:986: failed to build dll: exit status 1 - nojack.c:7:1: error: non-void function does not return a value [-Werror,-Wreturn-type]
            }
            ^
            1 error generated.

Fixes #42860.
