crecord: stop trying to import wcurses

The original import of crecord in 2008 already said "I have no idea if wcurses
works with crecord...".

The last reference to a Python package called wcurses is
https://web.archive.org/web/20101025073658/http://adamv.com/dev/python/curses/.
However, the Python package from there is called "curses" and not "wcurses".

I didn’t find any evidence that it ever worked.
