Subject: [PATCH] Update tinyfilemanager.php (#1268)

running envirement: Android 4.4+PHP 7.4.3+ KSWEB
http://192.168.1.2/tinyfilemanager.php, afer login,the main page could not be showed entirely,it just shows half of navigation bar.

that's becuase of
there are two same lines of codes which cause the problem. they are
$owner = posix_getpwuid(fileowner($path . '/' . $f));
when the funciton fileowner($path . '/' . $f)  return 0 and  run the function posix_getpwuid(....), it trig an error.
please check the codes in line 2156--2168 and 2221--2233

suggest replace these two parts with followed  codes:
                $owner = array('name' => '?');
                $group = array('name' => '?');
                if (function_exists('posix_getpwuid') && function_exists('posix_getgrgid')) {
                    try{
                        $owner_id = fileowner($path . '/' . $f);
                        if($owner_id != 0) {
                            $owner_info = posix_getpwuid($owner_id);
                           if ($owner_info) {
                                  $owner =  $owner_info;
                           }
                       }

                        $group_id = filegroup($path . '/' . $f);
                        $group_info = posix_getgrgid($group_id);
                        if ($group_info) {
                             $group =  $group_info;
                         }

                    } catch(Exception $e){
                       error_log("exception:" . $e->getMessage());
                    }
                }
