Remove skip_taskbar check (#355)

Current wine versions (with yabridge) do not provide SKIP_TASKBAR atom
so current implementation does not work at all for yabridge.
Reason SKIP_TASKBAR check was introduced because there was a edge case
with PixelComposer which spawned as popup instead of top level window.

That app spawns now normally as toplevel with both old and current wine
versions so removing the SKIP_TASKBAR check makes yabridge popups work
for any wine version.

Note:
After extensive testing wine-staging and non staging verisons they
report atoms very differenly:
wine-staging 9.21 reports all atoms in NET_WM_STATE while non stage and
anything above that report only single atom there or non at all
