Makefile: refactor GIT-VERSION-GEN to be reusable
Our "GIT-VERSION-GEN" script always writes the "GIT-VERSION-FILE" into
the current directory, where the expectation is that it should exist in
the source directory. But other build systems that support out-of-tree
builds may not want to do that to keep the source directory pristine,
even though CMake currently doesn't care.
Refactor the script such that it won't write the "GIT-VERSION-FILE"
directly anymore, but instead knows to replace @PLACEHOLDERS@ in an
arbitrary input file. This allows us to simplify the logic in CMake to
determine the project version, but can also be reused later on in order
to generate other files that need to contain version information like
our "git.rc" file.
While at it, change the format of the version file by removing the
spaces around the equals sign. Like this we can continue to include the
file in our Makefiles, but can also start to source it in shell scripts
in subsequent steps.
