For both mlir and polly, the lit internal shell is the default shell for running lit tests. However, if the user wanted to switch back to the external shell by setting `LIT_USE_INTERNAL_SHELL=0`, the `not` used in the body of the `if` conditional changes `use_lit_shell` to be True instead of the intended False. Removing `not` allows for this lit config to work as intended.
