prereq-build: require python3-distutils

Debian and Ubuntu ship a python3-minimal package which does not include
the distutils module. This is not supported by upstream and can be
considered a broken python distribution.

In practice, many scripts depend on said module, and this is a reoccuring
pain point for building various OpenWrt packages.

Require and check for said module, enough time has been wasted on this.
