[cifmw_cephadm] Fix log path when post.yml delegates to localhost

cifmw_cephadm_log_path uses ansible_user_dir which resolves to
/root on compute nodes running with become: true. The post.yml
and logs.yml tasks delegate_to: localhost to write log files, but
on the controller the zuul user cannot create directories under
/root.

Use cifmw_basedir (always /home/zuul/ci-framework-data in CI)
with a fallback to the original expression for non-CI contexts.
