[PATCH] Cygwin: console: Call fix_tab_position() only if having broken tabs.

- Calling fix_tab_position() is necessary in Windows 10 with xterm
compatible mode enabled, because it has a problem that the tab
positions will be broken when the window size is changed. Fortunately,
this problem has been fixed in Windows 11. Therefore, with this patch,
necessity of fix_tab_position() call is determined by referring to
wincap.has_con_broken_tabs(), which is recently introduced.
