binfmt_elf: use vmalloc() for allocation of vma_filesz
We have observed page allocations failures of order 4 during core dump while trying to allocate vma_filesz. This results in a useless core file of size 0. To improve reliability use vmalloc(). Note that the vmalloc() allocation is bounded by sysctl_max_map_count, which is 65,530 by default. So with a 4k page size, and 8 bytes per seg, this is a max of 128 pages or an order 7 allocation. Other parts of the core dump path, such as fill_files_note() are already using vmalloc() for presumably similar reasons.
