Implements 'adb bugreport <ZIP_FILE>'.

Dumpstate now supports zipped bugreport, whose output is more complete
than the flat-file bugreports provided prior to N. As such, adb now has
a 'adb bugreport <ZIP_FILE>' name whose implementation:

- Calls the new bugreportz binary.
- Parses its output, which in case of success is the path of the .zip
  file.
- Pulls the device file and renames it according to the command-line
  argument.
