BatteryMonitor: fix build error with health hal v2 updraged

Browse source 
libbatterymonitor_V1 is used for some libraries linking health
aidl_interface V1 but at the same time BatteryMonitor also uses
battery hal V2 structure, it will cause compiling error.

Folk BatteryMonitor is also required along with folk libbatterymonitor

Bug: 251425963
Test: build
