Replace use of deprecated Python module distutils.sysconfig

With Python 3.10, configure spits out warnings about the module
distutils.sysconfig being deprecated and scheduled for removal in
Python 3.12.  Change the uses in configure to use the module sysconfig
instead.  The logic stays the same.

Note that sysconfig exists since Python 2.7, so this moves the minimum
required version up from Python 2.6.
