python3: run-clang-tidy conversion

Upstream has not switched run-clang-tidy over to python3 yet but they
have done the changes needed to support it. OpenBMC is done with python2
so move clang-tidy over to python3 until upstream has an official change
for it.

Resolves openbmc/phosphor-state-manager#13

Tested:
Verified this change fixed the issue above and phosphor-state-manager
once again passes CI tests
