lint: Only include files in pytorch (#164008)

We were seeing instances of stdlib files in clang-tidy output so this
just essentially removes them from the things that lintrunner will
report up. Longer term fix here would be to just modify the clang-tidy
configuration in order to do the correct thing here but that requires a
bit more investigation as to why this is only happening in CI and is not
reproduceable locally.
