backtrace: use Java stack to help decode native

Before change:

  native: usb_host_run+16 [0x400a43f9] (/libusbhost.so)
  native: android::Vector<int>::do_move_forward(void*, void const*, unsigned int) const+54 [0x501b1c5b] (/libandroid_servers.so)
  native: ??? [0x624de480] (/system@framework@boot.oat)
  at com.android.server.usb.UsbHostManager.monitorUsbHostBus(Native method)
  at com.android.server.usb.UsbHostManager.access$000(UsbHostManager.java:38)

After change:

  native: usb_host_run+16 [0x400933f9] (libusbhost.so)
  native: android::Vector<int>::do_move_forward(void*, void const*, unsigned int) const+54 [0x4e984c5b] (libandroid_servers.so)
