Aligned bluetooth bugreport with PWG and fixed header/footer of DUMPSYS

1. After review by Privacy Working Group, android.hardware.bluetooth.IBluetoothHci/default service dumpsys is rejected due to PII
2. RunDumpsys(“title”,…) generates it's own header/footer which caused ABT(Android Bug Tool) not able to parse DUMPSYS. Removed “title” parameter so that RunDumpsys doesn’t generates it’s own header/footer.
