Previously, --without-python would cause ./configure to fail. Now it is able to proceed, and the Python scripts will not be built. Use portable parameter expansion matching instead of nonstandard substring matching to detect the Python version. This test is duplicated in several places, so define a function for it. Don't assume the full path to binaries, since different platforms do install things in different places. Use AC_CHECK_PROGS instead. When building without Python, also build without pyzfs.
