Kees Cook 5481dee296 coredump: Only sort VMAs when core_sort_vma sysctl is set

[ Upstream commit 39ec9eaaa1 ]

The sorting of VMAs by size in commit 7d442a33bf ("binfmt_elf: Dump
smaller VMAs first in ELF cores") breaks elfutils[1]. Instead, sort
based on the setting of the new sysctl, core_sort_vma, which defaults
to 0, no sorting.
