wine.inf: Fix the type of some values in HKLM, System\CurrentControlSet\Control\Session Manager\Environment

[Alexandru Balut]

Hi,

Fixes bug 8150.  http://bugs.winehq.org/show_bug.cgi?id=8150

The application mentioned in the bug sets "windir" to "%systemroot%"
which does not get expanded afterwards. I changed the type of some
Values to be REG_EXPAND_SZ, as it is on W2000.

Changelog:

HKLM,System\CurrentControlSet\Control\Session Manager\Environment
