Faster pre-commit by running ansible-lint only when necessary.

This patch disables ansible-lint `always_run` flag, as this was
making patches that did not change any YAML file take longer in
the pre-commit step, as ansible-lint was executed with no parameter,
thus, searching and evaluating all YAML files in the repository.

With this change, if no YAML file is modified, ansible-lint is skipped.
