DPP: Support DPP key_mgmt saving to wpa_supplicant configuration

In the existing code, there was no "DPP" string available to the DPP key
management type for configuration parser of wpa supplicant. When the
configuration is saved, the key management string was left out from the
config file. Fix this by adding support for writing key_mgmt=DPP option.
