docs: drop cross-build instructions for SE boot image

The SE VMs how-to documented building the s390x boot image on an x86_64
host via CROSS_BUILD=true TARGET_ARCH=s390x ARCH=s390x.

Cross builds are not exercised on our side and the supporting code has been
removed, so drop this instruction; the SE boot image is built on a native
s390x host.

### Adjust the configuration
There still remains an opportunity to fine-tune the configuration file:
