[PATCH v8 5/5] mingw/msvc: use the new-style RUNTIME_PREFIX helper




From: Johannes Schindelin <johannes.schindelin@xxxxxx>

This change also allows us to stop overriding argv[0] with the absolute
path of the executable, allowing us to preserve e.g. the case of the
executable's file name.

This fixes https://github.com/git-for-windows/git/issues/1496 partially.
