I checked w/ them that [lldb-x86_64-debian](https://lab.llvm.org/buildbot/#/builders/68) has python3-pexpect (specifically 4.8) installed.

Thanks! Cmake is still pretty foreign to me. It didn't occur to me that the result of finding a python library would be cached :) but I guess it makes sense from a build system perspective to not want to reconfigure everything all the time.

Since it sounds like all the bots should have `pexpect` now, I think I can flip the default later today and be ready to revert if there's unexpected breakage.
