Fix variable expansion syntax in .bat files

To expand a variable Windows cmd interpreter
requires variable name to be enclosed in percent
characters (%), not prefixed with just one.

post-install.bat:
Version test had always been true, which resulted in
rebase being done on *all* 32-bit Windows versions,
not only version 10 and above (as was intended).

setup-git-sdk.bat:
The same side effects as for post-install.bat.
