Alexander Egorenkov 242cbb3df9 s390/boot/vmlinux.lds.S: Ensure bzImage ends with SecureBoot trailer
commit ddc6cbef3e upstream.

Since commit 3e86e4d74c ("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.

Fixes: 3e86e4d74c ("kbuild: keep .modinfo section in vmlinux.unstripped")
