`UNICODE` and `_UNICODE` are not required when building git on Windows.
Actually, they should not be predefined at all.

There're 2 evidences that `(_)UNICODE` is supposed to be nonexist:

compat/win32/trace2_win32_process_info.c:83: It uses jw_array_string
which accepts pe32.szExeFile as const char*.

t/helper/test-drop-caches.c:16: Calling to GetCurrentDirectory with
Buffer as char*.

The autotools build system never defines `UNICODE` and `_UNICODE` and
builds on Windows well.

It _is_ true that we make a point of using the `*W()` suffix explicitly to
ensure that we use the Unicode variants of the Win32 API functions.

And it is also true that we do not explicitly define `UNICODE` in
`config.mak.uname`.

Therefore this patch is:

P.S.: Please note that the Git mailing list silently drops all mails from
@hotmail.com addresses, as far as I remember. Therefore, if you reply, it
may never reach the list.

Thanks for your remind! However, it seems that my reply reaches the list
successfully with hotmail address.
