linux_aura: Fix panel stickiness on GNOME 3.

While Unity and GNOME Classic had no problem processing a _NET_WM_STATE
change message on an unmapped window, this didn't work under GNOME
3. Take sky@'s previous suggestion of passing state in the InitParams,
which lets us coalesce this state bit with the rest of the pre-mapped
window property setting.

BUG=339399
TEST=Manually test on GNOME 3 that an always on top panel is sticky to all virtual desktops.
