Currently, an obtuse compiler diagnostic can fool kvm-find-errors.sh
into believing that the build was successful. This commit therefore
adds a check for a missing vmlinux file. Note that in the case of
repeated torture-test scenarios ("--configs '2*TREE01'"), the vmlinux
file will only be present in the first directory, that is, in TREE01
but not TREE01.2.
