menuconfig fix crash due to infinite recursion

gawk(1) tells that getline "returns 0 on end of file and -1 on an error." in current script for menuconfig if getline has an error,
it is still treated as true.

2.6 don't use that script anymore.

it is still treated as true, fix _both_ of its invocations.
