crecord: fallback to color = no when curses.use_default_colors() fails
Even when python was setup/compiled with curses, curses.use_default_colors()
may raise a curses exception when the TERM environment variable
specifies a value where no propper color configuration is possible.
This patch falls back to non-color mode to let the user continue
instead of failing with an unhandled exception.
