vmlinux is available for all the architectures, and suitable for running
a KVM guest by QEMU, besides, we used to copy the vmlinux to $resdir
anyway. Therefore it makes sense to use it as the fallback kernel image
for rcutorture KVM tests.
This patch makes identify_boot_image() return vmlinux if
${TORTURE_BOOT_IMAGE} is not set on non-x86 architectures, also fixes
several places that hard-code "bzImage" as $KERNEL.
This also fixes a problem that PPC doesn't have a bzImage file as build
results.
