The ABI files, which we use in Samba to check when we add new symbols
or change function arguments, need not to be dependent on python
versions, as Samba developers have multiple python3 versions installed,
but we only want one ABI file.
However, the vscript and the generated library needs to be python
The old code did this by removing the cpython... string from the ABI
file and symbol names before writing the file. You need to (carefully,
as it is now a shorter and less unique string) do the same.
