ktest: Handle kernels before make oldnoconfig 



When bisecting, one may come across a kernel that does not have
make oldnoconfig. In this case, we need to run the command "yes"
into a make oldconfig. This will select defaults instead of 'n'
into each command, but it works as a work around.

Note, "yes n" will not work because a config may have a value that
"n" is not acceptable for.
