Account for mem_node overhead inside cache_mem

This makes squid include the overhead memory space when determining the
number of data pages available in cache_mem memory space. Forming a much
better limit on memory cache usage.

This does NOT solve any issues created by sizeof(mem_node) being unaligned
with the system malloc implementation page size. That still needs to be
resolved.
