Log Message:
tests/libcurses: fix undefined behavior in test addch

The libcurses framework is not strictly typed and thus provides plenty
of ways to shoot yourself in the foot.  It's a waste of time debugging
things that a proper programming language can easily prevent.

The function addch expects an argument of type 'chtype'.  Passing a
"double-quoted" string does not match this, as 'chtype' is completely
different from a plain 'char'.  Instead, functions taking a 'chtype'
must be passed a `backtick-quoted` string.
