Please give some details of what is actually happening.
Include a [minimum complete verifiable example](https://stackoverflow.com/help/mcve) with
output of running `molecule --debug`.

Our test suite started failing with the 3.3.0 version of molecule. The prerun change that was added in #3077 started adding the current directory to ANSIBLE_LIBRARY. This can cause ansible to fail when there is a file with the same name as a module as can be seen here where ansible is trying to read setup.cfg in our project root as the setup module.

The problem seems to be in https://github.com/ansible-community/molecule/blob/60b68140fb5c650c47019f5db238c0864dbd43ed/src/molecule/provisioner/ansible.py#L943 In our case, after ansible-lint has run prepare_environment the ANSIBLE_LIBRARY envvar is :plugin/modules. I would think calling abs_path on this probably not appropriate since this is a colon separated path string and should just be read in unprocessed.
