python-common/deployment: rename a single letter variable

Rename a single letter variable name that was flagged by flake8. The
unique name `lbl` was chosen as it was short and didn't conflict with
any existing uses of the variable `label` in this file.

Part of an effort to get ceph tox environments passing on Python 3.12.
