generators/vcproj.pm: remove UNICODE from build

Defining UNICODE for MSVC IDE builds results in certain Win32 WIDE
API's receiving ANSI strings. The result of which is an invalid use
of the API and will end in either data corruption or an application
crash.

Prevent the use of WIDE API's when building with the MSVC IDE for
compatibility with msysGit.
