I added the option `-source-ignore` to the `run-clang-tidy.py` script in the
clang-tools-extra.
This option allows for handing over a regex, to ignore matching source files
from the compilation database (not run `clang-tidy` on them).
**Why "ignore" instead of "filter"?**
I found it more useful to actively filter out (ignore) source files, rather
than the inverse logic. One usually knows where the source files reside and can
now easily ignore e.g. the `thirdparty/` directory.
