Subject: [PATCH] Replace pipes.quote with shlex.quote in configure.py

Python 3.12 deprecated the pipes module and it will be removed
in Python 3.13. In configure.py, I have replaced the usage of pipes.quote
with shlex.quote, which is the exactly same function as pipes.quote.

For more details, refer to PEP 0594: https://peps.python.org/pep-0594
