Python: replace src_archive exclusion patterns with *.testproj ones

The `**/src_archive/**` exclusion patterns seem to have to do with
trying to exclude archived source files from being picked up for the
extractor while running the test itself. However it seems that directory
is not being used any more by `codeql` (which uses a `src` directory
instead).

A `*.testproj` exclusion pattern will work in a more robust way, by
excluding any file inside the database being built.
