nommu: vmalloc_32_user()/vm_insert_page() and symbol exports.

Trying to survive an allmodconfig on a nommu platform results in many
screen lengths of module unhappiness.  Many of the mmap related things that
binfmt_flat hooks in to are never exported despite being global, and there
are also missing definitions for vmalloc_32_user() and vm_insert_page().

I've implemented vmalloc_32_user() trying to stick as close to the
mm/vmalloc.c implementation as possible, though we don't have any need for
VM_USERMAP, so groveling for the VMA can be skipped.  vm_insert_page() has
been stubbed for now in order to keep the build happy.
