contrib/bsddialog: Import version 1.0.2
Implicitly import also 1.0.1, both versions are for fixing and
feature requests.

Fixing:
Change --mixedform behavior to fix a bsdinstall fault avoiding
to change the command line in wlanconfig.

Feature requests:
 * Add keys to navigate menus.
 * Add key to redraw dialogs.
 * Avoid to handle env NCURSES_NO_UTF8_ACS in PuTTY.

See '2024-04-11 Version 1.0.2' and '2023-11-16 Version 1.0.1' in
/usr/src/contrib/bsddialog/CHANGELOG for more detailed information.
