Reduce duplication among *printf-posix modules

[Bruno Haible]

For each of the *z*printf modules, I'll add a -posix and a -gnu variant.
In order to avoid code duplication between the module descriptions,
here are two patches that introduce a "mixin" module for the -posix
variant and likewise one for the -gnu variant.

These modules cannot be used on their own, and are a private detail.
The term "mixin" obviously refers to the concept of mixin classes
in various object-oriented languages.
