lrdpv2: Ensure that QTF parsing is thread-safe
The debug_image_v2 module's usage of QTF to extract Ftrace log information currently relies on a single QTF server process, and communicates with that server process via a fixed port ID. Any other instances of the ramdump parser running in parallel will also use this same server and port ID, which presents a race condition if multiple instances attempt to parse QTF input files simultaneously. To deal with this problem, each ramdump parser instance must instead create and communicate with its own QTF server process via a unique port ID. Change-Id: Ic9c53003789dca229d1e2770d01aa15a702292a7
