Bug 1914478: Replace usage of stdlib pipes library with shlex

Python 3.13 removed the already deprecated "pipes" module from the
standard library.
Some files were using the "quote" function from pipes, which prior to
3.13 was a re-export of a function with the same name in "shlex".

This change imports the shlex module directly.
