color: make a test for curse availability explicite

We won't use terminfo when curse failed to load. Before this change, we were
doing an indirect test, relying on the fact some variable ('_terminfo_params')
would be empty if curses failed to load. We update the code to be more explicit
and directly checks if we managed to load the curse module.
