Truly fix Classloader crash in com.android.phone

The previous attempted fix did not work because the
TelephonyComponentFactory's classloader also did not have access to the
Android HIDL manager library. It was missed because the exception was
caught and printed to the radio logs instead of the system logs.

This fix adds the Android HIDL manager .jar path to the PathClassLoader
making it available to the caller.

Test: verified crash message no longer displays in the home screen,
crash dump no longer appears in "adb logcat" and no errors are printed
to logcat radio logs.
