[lldb][test] Disable TestMultipleDebuggers again

I did manage to turn a crash into a non-zero return code,
but on the very first build it managed to time out.

I thought I had the appetite to tweak timeouts but
on second thought, I don't want yet another test to look
out for.

The test is not wrong, but on heavily loaded machines
it's always going to be inherently unstable.
