cros: Init SystemTrayDelegate earlier to break bluetooth init dependency

This is needed to allow TrayBluetoothHelper to move into //ash, which is
required to get Bluetooth working in mutash.

SystemTrayDelegateChromeOS used to have a two-step initialization process
with some code being initialized after the Bluetooth adapter becomes
available. I think that init doesn't need to wait on Bluetooth init.
