avidemux: remove duplicate .desktop file
https://github.com/void-linux/void-packages/pull/35400

Description:
By default, avidemux has used `org.avidux.avidux.desktop`. So, I try to delete `avidemux.desktop` because it could not be executed.

```
➜  ~ xbps-query --regex -Rf avidemux | grep desktop
/usr/share/applications/avidemux.desktop
/usr/share/applications/org.avidemux.Avidemux.desktop
```
