build: prefer WIN32 over __MINGW32__ checks

WIN32 is always defined when __MINGW32__ is defined, but the
converse is not true.  WIN32 is more generic, if someone were
to ever attempt porting to a microsoft compiler.  This does
not affect Cygwin, which intentionally does not define WIN32.

* src/qemu/qemu_driver.c (qemuDomainGetBlockInfo): Use more
generic flag macro.
* src/storage/storage_backend.c
(virStorageBackendUpdateVolTargetInfoFD)
(virStorageBackendRunProgRegex): Likewise.
* tools/console.h (vshRunConsole): Likewise.
