From: Lev Stipakov <[email protected]>
Since wmic has been recently deprecated and is absent on new
systems, replace setting DNS domain "old-style" with powershell.
This is based on 2.6 patch which replaces wmic with powershell
d383d6e "win: replace wmic invocation with powershell"
except that here we only touch openvpn process code. There is no
wmic calls in 2.7 service.
Github: fixes OpenVPN/openvpn#642
