hardwareprofile: remove ancient "future" compatibility library for py…

…thon2

Ironically, for a package that was intended to provide portability
between python2 and python3, it is broken with python 3.12. A better
library to use in all cases is "six".

However, mythtv requires python 3.8 for a while now. Using
"future.standard_library" is a no-op other than costing a pointless
import and being troublesome to actually install.

The hacky copy of six.with_metaclass included in "future" is rewritten
to use the pure python3 form of a metaclass.
