Tobias Waldekranz d16ad7eedc build: Define build id and version in one place
Before this change, setting `GIT_VERSION` in `make`'s environment was
intended to allow the user to specify a custom build id.  As it turns
out, `test/test.mk` had duplicated the logic from
`board/common/post-build.sh` to unconditionally override any value set
in it.  Because of the way `make` handles variables, where assignments
to variables inherited from the environment are exported back to
it[^1], this would mean that `test.mk` would always clobber any value
set by the user.  Furthermore, there is also this file called
`buildroot/package/git/git.mk`, which also (reasonably) has opinions
about what the proper value of `GIT_VERSION` should be.  In summary,
this was a bit of a mess.

Therefore: Make sure that there is one single place where we determine
the build id and version, and make sure that those variables are
scoped under the `INFIX_` prefix to avoid clashing with any other
component.
