Adjust rust beta-sysroot install path format on windows
The upstream install scripts are .sh files and aren't well-equipped to
handle windows filepaths. Empirically, it seems that on windows we need
to pass a relative path in posix format (forward slashes). Otherwise,
it will put the sysroot in various odd locations (including possibly
some that are impossible to create by normal methods, e.g. those with a
colon in the name).
