  Fix Issue 22212 - dmd version has -dirty suffix on windows

  Typically, git-clone probes the filesystem to see if it handles the
executable bit correctly and the `core.fileMode` variable is automatically set
as necessary. However when building dmd releases using vagrant box method,
git-clone is done on a Linux host (i.e a filesystem that handles the filemode
correctly), then scp'd to a Windows VM (i.e an environment that loses the
filemode). So when building Windows binaries, always ensure this variable is
set to `false`.
