scripts/get_abi: fix source path leak

commit 5889d6ede53bc17252f79c142387e007224aa554 upstream.

The code currently leaks the absolute path of the ABI files into the
rendered documentation.

There exists code to prevent this, but it is not effective when an
absolute path is passed, which it is when $srctree is used.

I consider this to be a minimal, stop-gap fix; a better fix would strip
off the actual prefix instead of hacking it off with a regex.
