cml1.bbclass: Fix return code handling in do_menuconfig()

On my system, doing "bitbake -c menuconfig busybox" pops up
a gnome-terminal, I can see that the compilation starts but then the
terminal automatically exits.

It turns out I don't have ncurses development package installed on my host,
and OE's host sysroot isn't being passed to gcc, so compilation fails.
The window automatically closes before I can read the error message
since the '$' in the return code check needs to be escaped.

Make sure the user can read the error message by properly checking the
return code.
