clang-format: Adjust Mozilla style defaults

[poiru]

Summary

This makes the Mozilla style defaults more compliant with the Mozilla style guide. A few options were removed in order to use the LLVM style defaults.

Looks good. I agree that either the coding style directly mentions these or a look at some random source files shows that these options are closer to what is currently used.
