lts kernel flavor results in broken /sysroot mount path

[natesales]

When building an image with the lts kernel-flavor, the resulting image isn't able to find the root fs to mount.

I'm using sudo ./alpine-make-vm-image --image-format qcow2 --kernel-flavor lts alpine-test.qcow2 to build the image and sudo kvm -smp 8 -drive file=alpine-test.qcow2 to test in qemu. Replacing the kernel-flavor with the default virt kernel works just fine.
