Incorrect $HOME value when using runas on Windows

From: Mail <hidden>
Date: 2021-01-20 11:33:20

To reproduce the issue:
1. Install git-windows x32 or x64 for all users.
2. Install Total Commader or any other file manager that support system 
context menu
3. Add user in Windows via msc or settings app and set password. Don't 
forget to disable "User must change password on first login" in case 
user created via msc
4. In current user session execute runas.exe /user:NewlyCreatedUser 
"Path To File Manager"
5. Right click on empty space in file list and choose Git bash here
6. Type `echo $HOME` in bash console and press enter
7. The $HOME is `/c/Windows/System32`. Expected `/c/Users/NewlyCreatedUser`
It seems git for windows uses HOMEPATH that points to system32 in case 
of runas command. Might be using USERPROFILE variable is better.

I'd recommend reporting this to the Git for Windows project[0].  The
setting of $HOME is normally a feature provided automatically by
Unix-like operating systems, and its behavior in the MSYS environment is
controlled by Git for Windows.

There is actually already a ticket about this:
https://github.com/git-for-windows/git/issues/2709

I integrated a patch that fixes this from `git.exe`'s side, but had
forgotten the `git-bash.exe` side. Here is a PullRequest to address this:

	https://github.com/git-for-windows/MINGW-packages/pull/45

Mail (if this is your real name, if not, please substitute your real name
in your mind), feel free to test that PR's code and report back whether it
solves your problem or not.

Ciao,
Johannes
