rtv: Add a TODO to document a problem with py-curses

Unfortunately I've still not investigated in depth why it fails in that ways.
At the moment, the only workaround know is to recompile py-curses with
`CURSES_TYPE=ncurses'.

+When built against devel/py-curses CURSES_TYPE=curses on NetBSD (tested with
+8.99.1), at run-time it fails with:

+
+Investigate why it fails in that way (only CURSES_TYPE=curses is affected,
+rebuilding or having a py-curses built with CURSES_TYPE=ncurses doesn't expose
+this problem).
