pc-bios/s390-ccw: zero out bss section
The QEMU ELF loader does not zero the bss segment.
This resulted in several bugs, e.g. see
commit 5d739a4787a5 (s390-ccw.img: Fix sporadic errors with ccw boot image - initialize css)
commit 6a40fa2669d3 (s390-ccw.img: Initialize next_idx)
commit 8775d91a0f42 (pc-bios/s390-ccw: Fix problem with invalid virtio-scsi LUN when rebooting)
Let's fix this once and forever by letting the BIOS zero the bss itself.
