Android: Pass the vendor events to $(BOARD_HOSTAPD_PRIVATE_LIB)

Introduce a new board configuration via
$(BOARD_HOSTAPD_PRIVATE_LIB_EVENT) rather than reusing
$(BOARD_HOSTAPD_PRIVATE_LIB) to pass vendor events handling in the
hostapd private library. This is to avoid compilation issues for
wpa_driver_nl80211_driver_event() with the already existing private
library implementations defined with $(BOARD_HOSTAPD_PRIVATE_LIB).

This is similar to the existing BOARD_WPA_SUPPLICANT_PRIVATE_LIB_EVENT
parameter for the wpa_supplicant build.
