test: Enable to test custom CPU templates w/o python code modification

Previously to test custom CPU templates for temporary testing purpose in
development, we needed to modify Python code (especially
tests/framework/utils_cpu_templates.py) manually. That is very
cumbersome and slows down our development / test / debug cycle, since it
requires us to make a commit and push it manually.

With this change, we become able to inject custom CPU templates into
test (not only from local but also from buildkite) without modifying
python code.
