  ncurses: fix CVE-2025-6141 buffer overflow in postprocess_termcap

Backport buffer-limit check from ncurses 6.5-20250329 (fix by
Thomas Dickey, report/testcase by Yifan Zhang).

The ko capability processing loop in postprocess_termcap() copies
termcap string values into buf2[MAX_TERMINFO_LENGTH] without bounds
checking, allowing a stack-based buffer overflow via a crafted
termcap entry.
