The construction of the combined svc-map-services file uses the host's /tmp directory to store a work-in-progress file. That file's left behind after it's done with. There's a potential race here; together with problems that may arise if two users attempt to run devtest on the same system. This patch fixes this by creating the temporary file specifically under $TMP_MOUNT_PATH. Change-Id: Iecbdc583e37bed542249c316919c3712c28c7440
