LOG: [lldb][test] Double the timeout for TestGuiSpawnThreads.py (#210043)

If the host machine is overloaded, spawning threads may be delayed due
to lack of resources. I'm pretty sure this is the cause of failures in
GitHub CI reported in
https://github.com/llvm/llvm-project/issues/209874.

For what the test is doing, we unfortunately cannot get around needing
to wait on the test program.

We could perhaps come up with a lit mode that runs some tests in serial,
but this is a larger project than I want to get into now.

For now, let's try doubling the timeout. This test is unlikely to fail
for real, so if it's taking a long time, it'll be due to system
resources. In 99% of cases, it'll pass in a few seconds still.
