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.
