mm: ifdef Quicklists in /proc/meminfo

A "Quicklists:          0 kB" line has just started appearing in
/proc/meminfo, but most architectures (including x86) don't have
them configured, so #ifdef it, like the highmem lines.

And those architectures which do have quicklists configured are
using them for page tables: so let's place it next to PageTables.
