Revert "Qt: set breeze as default theme"

This reverts commit 31d935254b3156429958bb6c5407a106456e9162.

Now that we are adding kali purple themes I've noticed that breeze qt
theme doens't follow the color-palette everywhere. In some cases it
still shows the blue highlight color.
Plus installing it in Xfce as an example takes 40MiB (unpacked)
