Export symbol __lock_task_sighand, so it is accessible from code compiled as modules. This fixes the following modpost error: ERROR: modpost: "__lock_task_sighand" [net/9p/9pnet.ko] undefined!
Where __lock_task_sighand is called via lock_task_sighand in net/9p/client.c See https://lore.kernel.org/lkml/20200620201456.14304-1-alexander.kapshuk@gmail.com/.
