Fix `is_terminal`'s handling of long paths on Windows.

As reported in sunfishcode/is-terminal#18, there are situations where
`GetFileInformationByHandleEx` can write a file name length that is
longer than the provided buffer. To avoid deferencing memory past the
end of the buffer, use a bounds-checked function to form a slice to
the buffer and handle the out-of-bounds case.

This ports the fix from sunfishcode/is-terminal#19 to std's `is_terminal`
implementation.
