Ubuntu 1b457bcbe5 Fix vmem_size()
Add a minimal implementation of vmem_size() which accounts for the
virtual memory usage of the SPL's kmem cache.  This functionality
is only useful on 32-bit systems with a small virtual address space.

The following assumptions are made:

  1) The major SPL consumer of virtual memory is the kmem cache.
  2) Memory allocated with vmem_alloc() is short lived and can be ignored.
  3) Allow a 4MB floor as a generous pad given normal consumption.
  4) The spl_kmem_cache_sem only contends with cache create/destroy.
