Alexandre Alapetite 45ee7a36d5 PHP8: SimplePie wrong use of isset (#3404) ...

#fix https://github.com/FreshRSS/FreshRSS/issues/3401 (crash with PHP 8+)

`ceil()` crashes in PHP8+ in case of invalid input such as empty string.
`intval()` fixes the problem with almost identical behaviour than `ceil()` in PHP7- (except for floating point values)

#fix FreshRSS/FreshRSS#3401 (crash with PHP 8+)

Example with feed http://podcast.hr2.de/derTag/podcast.xml

```xml
<enclosure url="https://mp3podcasthr-a.akamaihd.net:443/mp3/podcast/derTag/derTag_20210129_87093232.mp3"
length="" type="audio/mpeg"/>
```

`isset("")` passes and then `ceil("")` crashes due to wrong type in PHP8+:

```
Uncaught TypeError: ceil(): Argument #1 ($num) must be of type
int|float, string given in ./SimplePie/SimplePie/Item.php:2871
```
