[knst]

Issue being fixed or feature implemented

Resolves build failures with Python 3.12, i.e building on rawhide:

  make -C depends -j9
  ...
  make[3]: Nothing to be done for 'install-exec-am'.
   /usr/bin/mkdir -p '/bitcoin/depends/work/staging/aarch64-unknown-linux-gnu/xcb_proto/1.14.1-4a91ac9dc41/bitcoin/depends/aarch64-unknown-linux-gnu/lib/python3.12/site-packages/xcbgen'
   /usr/bin/install -c -m 644 __init__.py error.py expr.py align.py matcher.py state.py xtypes.py '/bitcoin/depends/work/staging/aarch64-unknown-linux-gnu/xcb_proto/1.14.1-4a91ac9dc41/bitcoin/depends/aarch64-unknown-linux-gnu/lib/python3.12/site-packages/xcbgen'
  Traceback (most recent call last):
    File "<string>", line 2, in <module>
  ModuleNotFoundError: No module named 'imp'
  make[3]: *** [Makefile:271: install-pkgpythonPYTHON] Error 1

imp was removed in 3.12: https://docs.python.org/3/library/imp.html.
