[committed][gdb/testsuite] Fix gdb.threads/fork-plus-threads.exp timeout with check-run1

[Tom de Vries <tdevries@suse.de>]

Hi,

With gdb.threads/fork-plus-threads.exp and check-run1 we get:
...
FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: \
  inferior 1 exited (timeout)
...

Fix this by calling exp_continue for new thread and thread exited messages.

Tested on x86_64-linux.

Committed to trunk.

Thanks,
- Tom
