testsuite, threads: add missing return statements

Add missing return statements in

  * gdb.threads/process-exit-status-is-leader-exit-status.c
  * gdb.threads/next-fork-exec-other-thread.c

to fix 'no return statement' compiler warnings, e.g.:

  process-exit-status-is-leader-exit-status.c: In function ‘start’:
  process-exit-status-is-leader-exit-status.c:46:1: warning: no return
    statement in function returning non-void [-Wreturn-type]
     46 | }
        | ^
