healthimpl: switch to KLOG_* for logging

Using ALOG* works fine to get logs from logcat. In some cases,
it's observed that with more log spew from userspace entities,
logs from healthimpl is missed out or wrapped around. To get
useful information like how much time we've waited for battery
power supply capacity property, switch to KLOG_* APIs so that
these logs are part of kernel logs.
