tox: Remove bandit skips, run via pre-commit

Most of these skips were unnecessary. The few that did generate warnings
could be skipped.

We also set 'skip_install' since there's no reason to build the package
for linting purposes.

-# This command runs the bandit security linter against the openstackclient
