drm: Track clients by tgid and not tid
Thread group id (aka pid from userspace point of view) is a more interesting thing to show as an owner of a DRM fd, so track and show that instead of the thread id. In the next patch we will make the owner updated post file descriptor handover, which will also be tgid based to avoid ping-pong when multiple threads access the fd.
