Cygwin: console: Fix SIGWINCH handling in Win7.
- If ENABLE_VIRTUAL_TERMINAL_INPUT is not set, changing window height
does not generate WINDOW_BUFFER_SIZE_EVENT. This happens if console
is in the legacy mode. Therefore, with this patch, the windows size
is checked every time in cons_master_thread() if the cosole is in
the legacy mode.
