Fix ClassLoader crash in com.android.phone

The custom PathClassLoader was not loading the .jar required for the
V1.0 HIDL manager class. This change switches to the ClassLoader of the
TelephonyComponentFactory (used by the com.android.phone app) which has
access to all required libraries.

Test: verified crash message no longer displays in the home screen and
crash dump no longer appears in "adb logcat"
