Subject: [PATCH] kernel: os_SUITE: fix close_stdin test

* os_SUITE_data/my_fds.c:
  read(stdin, buff, 1) is invalid because stdin is a FILE* and not an
  fd, will become an error by default in clang 16.
* os_SUITE.erl:
  my_fds program now returns 0 bytes read instead of -1 for error,
  update assertion.
