spectator_hud: move to layer 2 (#3505)

* spectator_hud: move to layer 2

Spectator HUD enables/disables ecostats depending on the amount of ally
teams in the game. If there are exactly two teams (in addition to Gaia),
then Spectator HUD is enabled. If there are not exactly two teams, i.e.
it's an FFA game, then Ecostats is enabled.

However, this logic requires we make sure the Initialize() of Spectator
HUD runs after Ecostats. If the widgets are in the same layer or
Spectator HUD is on an earlier layer, both Spectator HUD and Ecostats
are enabled at the same time after loading a FFA game.
