adb: win32: fix regression on older versions of Windows

On Windows 7, GetStdHandle() may return console pseudo-handles. If you
call SetHandleInformation(h, HANDLE_FLAG_INHERIT, 0) on such a handle,
it will fail. These failures should be ignored like the old code.

Newer versions of Windows return real handles that don't have this
issue. Console pseudo-handles can apparently be identified by the values
3, 7, 11.

This is a regression from 2122c7a1.
