s390/boot/vmlinux.lds.S: Ensure bzImage ends with SecureBoot trailer
Since commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped") the .modinfo section which has SHF_ALLOC ends up in bzImage after the SecureBoot trailer. This breaks SecureBoot because the bootloader can no longer find the SecureBoot trailer with kernel's signature at the expected location in bzImage. To fix the bug, move discarded sections before the ELF_DETAILS macro and discard the .modinfo section which is not needed by the decompressor.
