spa: bluez: backend-native: accept "=" for +VGS and +VGM

Browse source 
HFP 1.8 states in 4.35.1:

  Due to the small inconsistency between the GSM standard [2]) and the current
  Headset specification ([3]), the HF shall also accept the “=” symbol,
  in place of “:”, as a valid separator for this unsolicited result code.

iOS seems to use "=", so accept that as well.

See #2463
