crecord: stop raising error.Abort if curses is not found (issue5008)

On some servers, python curses support is disabled. This patch not only fixes
that but provides a fallback on other machines (e.g. Windows) when curses is
not found.

The previous code was actually flawed logic and relied on wcurses throwing an
ImportError which demandimport wouldn't throw. So, this patch also fixes that
problem.
