vboot: add flag to indicate that the EC is slow to program

Browse Source 
Some EC's are slow to program their firmware. This could happen at any boot
as part of software sync. This adds the VB_INIT_FLAG_EC_SLOW_UPDATE input
flag to VbInit(), so that vboot knows to display the EC-is-being-programmed
screen when that flag is set.
