Add negative integration tests for close syscalls

Add three negative scenarios to verify ior captures tracepoints even when
close syscalls fail:

- close-invalid-fd: close an fd (99999) that was never opened (EBADF)
- close-double-close: open a file, close it, close same fd again (EBADF)
- close-range-empty: close_range on high fd range with no open fds
