utils/genrandconfig: drop glibc Linaro toolchain version check

It has been well over 10 years since glibc 2.14 was released; the last
Debian version that had an earlier glibc was Wheezy, which Freexian
stopped to maintain as an ELTS in June 2020, 4 years ago, while the
oldest still maintained Ubuntu has glibc 2.21. It is now safe to assume
glibc 2.14 on all major, relevant distributions nowadays.

The distutils module is no longer bundled with python 3.12 so this
eliminates the need to install additional python modules under python
3.12.
