Fix import circularity

state.py imports both utils.robot (and lib/state_manager.robot which
imports utils.robot).  utils.robot imports lib/boot_utils.robot which
ultimately tries to import state.py.  This creates a circular import
stack which causes failures:

[ WARN ] Imported library 'lib/state.py' contains no keywords.
[ ERROR ] Error in file 'extended/obmc_boot_test_resource.robot':
  Importing test library 'lib/obmc_boot_test.py' failed:
  AttributeError: 'module' object has no attribute 'return_state_constant'

state.py no longer has need of utils.robot or state_manager.robot so
references to them are being deleted.
