splitmuxsrc: Use natural ordering to find files

Browse source 
Today when using the `splitmuxsrc` on a collection of files named as:

```
item0.mkv
item1.mkv
item2.mkv
[...]
item10.mkv
item11.mkv
[...]
```

You will get a continuous stream made in the order of:

```
item0.mkv -> item1.mkv -> item10.mkv -> item11.mkv -> [...]
```

You can fix this by having smarter names of the items:

```
item000.mkv
item001.mkv
item002.mkv
[...]
item010.mkv
item011.mkv
[...]
```

Will get you:
```
item000.mkv -> item001.mkv -> item003.mkv -> item004.mkv -> [...]
```

But, we could also "fix" the former case by using natural ordering when
comparing the files in gstsplitutils.c.

Fixes #2523
