Allow the clang-tools scripts to work with builds in tools such as
tools/perf and tools/lib/perf. An example use looks like:
```
$ cd tools/perf
$ make CC=clang CXX=clang++
$ ../../scripts/clang-tools/gen_compile_commands.py
$ ../../scripts/clang-tools/run-clang-tools.py clang-tidy compile_commands.json -checks=-*,readability-named-parameter

Fix a number of the more serious low-hanging issues in perf found by
clang-tidy.
This support isn't complete, in particular it doesn't support output
directories properly and so fails for tools/lib/bpf, tools/bpf/bpftool
and if an output directory is used.

arguments
