[PATCH] manual: adjust reference to man-pages following proc(5) split-up

The reference to MAP_NORESERVE and /proc/sys/vm/overcommit_memory was
moved from proc(5) to proc_sys(5) in man-pages commit bfc1299e7 (proc.5,
proc_sys.5: Split /proc/sys/ from proc(5), 2023-08-15). It was
subsequently moved to proc_sys_vm(5) in man-pages commit
b06cd070f (proc_sys.5, proc_sys_vm.5: Split /proc/sys/vm/ from
proc_sys(5), 2023-09-30).
