lib: Report file cache as available system memory
sysinfo() doesn't include all reclaimable memory. In particular it
excludes the majority of global_node_page_state(NR_FILE_PAGES),
reclaimable pages that are a copy of on-disk files It seems the only way
to obtain this counter is by parsing /proc/meminfo. For comparison,
check vm_enough_memory() which includes NR_FILE_PAGES as available
(sadly there's no way to call vm_enough_memory() directly either!)
v2: Pay attention to what one writes.
v3: Trim off redundant space, and warn if the requested tags do not
match the layout of /proc/meminfo.
