tests: allow Google's internal builds of clang-format to be used
These builds do not actually include any Google-specific formatting changes; the
only reason they don't include the LLVM version number is due to a decision to
elide the version number from *all* LLVM/clang projects.
For most builds of clang-format, even "unofficial" ones, the LLVM version will
be displayed; example:
```
clang-format version 14.0.0 (https://github.com/llvm/llvm-project.git 1830ec94ac022ae0b6d6876fc2251e6b91e5931e)
```
The Google-internal build looks like this:
```
clang-format version google3-trunk (1830ec94ac022ae0b6d6876fc2251e6b91e5931e)
```
