test: fix build for macOS Sequoia 15.0

When building <tarantool-c-tests/gh-8594-sysprof-ffunc-crash.test.c> on
macOS Sequoia 15.0, I've got the following error from including
<sys/ptrace.h>:

| error: unknown type name 'caddr_t'
| int     ptrace(int _request, pid_t _pid, caddr_t _addr, int _data);

It can be fixed by including <sys/types.h>, but since this test is
skipped for macOS anyway, I prefer just to move all necessary includes
under the corresponding define.
