adb: fix for SuperSpeed devices

Browse Source 
The USB descriptor parsing in adb fails to detect SuperSpeed devices
because of the SuperSpeed Endpoint Companion Descriptor.  This
cherry-picks the upstream fix for the problem.

Unfortunately there never were a release with this fix before the
conversion to C++, so upgrading to a newer version isn't an option.

This makes adb work with SuperSpeed devices like the Sierra Wireless
EM7565.  Tested and verified.

Subject: [PATCH] ADB on linux: Handle USB SuperSpeed extra Descriptors
Under Linux, ADB manually parses USB Descriptors to check for
possible ADB USB Interfaces. USB Devices connected with SuperSpeed
will exhibit extra USB SuperSpeed Endpoint Companion Descriptors.
This patch handles these USB SuperSpeed specific USB Descriptors.
