Replace all fwrite/fread/fgets/... to write/read/...
Before:
```
text data bss dec hex filename
109827 601 6608 117036 1c92c nuttx/nuttx
```
After:
```
text data bss dec hex filename
108053 601 6608 115262 1c23e nuttx/nuttx
```
After with CONFIG_FILE_STREAM disabled:
```
text data bss dec hex filename
105667 601 6608 112876 1b8ec nuttx/nuttx

since it is wrong to close the builtin stream and specially note
https://pubs.opengroup.org/onlinepubs/9699919799/functions/fclose.html:
Since after the call to fclose() any use of stream results in
undefined behavior, fclose() should not be used on stdin, stdout,
or stderr except immediately before process termination (see XBD
Process Termination), so as to avoid triggering undefined behavior
in other standard interfaces that rely on these streams. If there
are any atexit() handlers registered by the application, such a
call to fclose() should not occur until the last handler is
finishing. Once fclose() has been used to close stdin, stdout, or
stderr, there is no standard way to reopen any of these streams.
and it is also unnecessary because the stream always get flushed.
