cephadm: work around pip failure on some envs

Work around an encoding/locale issue when the dashboard tests are run
(ubuntu 20.04).
The build.py changes brought in a9d1c62ca86 were validated for package
builds, teuthology, and other CI jobs but a different error was masking
this failure in the dashboard ci job.
