Adjust clang-format name in script to be parameterized
After merging legacy/trac#32921 (moved), we'll need to adjust our code reformatting script so that it can handle the case where clang-format >= 6.0 is not named "clang-format", but instead something else.
I'd lean towards an environment variable, something like TOR_CLANG_FORMAT
, but I don't feel too strongly and I'm open to other ideas too.
