Matthias Krüger 93daf27a40 tests: ignore check_that_clippy_has_the_same_major_version_as_rustc() inside the rustc repo.
Do not check if clippy version matches rustc version when runnning tests inside the rustc repo.
This makes sure that upstream rustc maintainers do not have to deal with our test failing/mismatching versions
when the rustc version bump is happening.
