s390/vmlinux.lds.S: Move .vmlinux.info to end of allocatable sections

When building s390 defconfig with binutils older than 2.32, there are
several warnings during the final linking stage:

  s390-linux-ld: .tmp_vmlinux1: warning: allocated section `.got.plt' not in segment
  s390-linux-ld: .tmp_vmlinux2: warning: allocated section `.got.plt' not in segment
  s390-linux-ld: vmlinux.unstripped: warning: allocated section `.got.plt' not in segment
  s390-linux-objcopy: vmlinux: warning: allocated section `.got.plt' not in segment
  s390-linux-objcopy: st7afZyb: warning: allocated section `.got.plt' not in segment

binutils commit afca762f598 ("S/390: Improve partial relro support for
64 bit") [1] in 2.32 changed where .got.plt is emitted, avoiding the
warning.

The :NONE in the .vmlinux.info output section description changes the
segment for subsequent allocated sections. Move .vmlinux.info right
above the discards section to place all other sections in the previously
defined segment, .data.
