Makefile: propagate Git version via generated header
We set up a couple of preprocessor macros when compiling Git that
propagate the version that Git was built from to `git version` et al.
The way this is set up makes it harder than necessary to reuse the
infrastructure across the different build systems.
Refactor this such that we generate a "version-def.h" header via
`GIT-VERSION-GEN` instead.
