Run clang-tidy with default configuration on all files listed in the
compilation database. Note that the generated files in the build directory
have to be built first. The simplest way to achieve this is to build libVirt
first.
Example:
$ meson build && ninja -C build
$ ./scripts/run-clang-tidy.py -p build
