LOG: Revert "Reapply "[llvm] Use lit internal shell by default""

This reverts commit f869d7a1b100c9f9fc5bb06effcf4f73346c0919.

This broke some debuginfod tests that are not run by default in most CI
configurations. Reverting for now until I have time to update the tests
and figure out how to get them built locally.
