Patch

I noticed on a host without icecc installed, calls to "Tools/Script/update-webkitwpe-libs" end up on the following error:

```
$ Tools/Scripts/update-webkitwpe-libs 
Updating Flatpak Release environment
error: Unable to allocate instance id

```

I think function setup_icecc(), which ends up running icecc, should only be called if flag use_icecream was set.
