python: Fix compile for in-tree builds

python: Fix compile for in-tree builds

Without a separate build tree the source files have relative paths,
so the build rules must not change the directory.

LGTM

Thanks Jonas, it works like a charm.

If it doesn't break out-tree build, I think you might push directly.

LGTM 

Please push immediately; all my QA scripting is broken at the moment.

    Issue 5910: python: Fix compile for in-tree builds
    
    Without a separate build tree the source files have relative paths,
    so the build rules must not change the directory.
