Changing SUPL_ES=1 for SUPL end point control

SUPL_ES=1 ensures the GnssLocationProvider and related framework code
accepts incoming SMS SUPL_INIT messages with ES-bit=1
(which allow redirection of the ESLP
end-point e.g. to the current local emergency services provider when
you are travelling) only during an emergency call
