fix a compiler warning with (Net)BSD curses

Some curses implementations have tparm(char *) (BSD and older ncurses), some
have tparm(const char *).

The older POSIX specification had: tparm(char *):
https://pubs.opengroup.org/onlinepubs/7908799/xcurses/term.h.html

Just cast it to char *. The terminfo variables are defined elsewhere so it
should be safe.

Also remove an unnecesary cast in minicurses.

Hopefully this satisfies all curses variants and versions now.
