[PATCH] Fix kernel build with EMBEDDED & PROC_FS & !PROC_SYSCTL

Without attached patch against current -git I get following with
!PROC_SYSCTL (with EMBEDDED and PROC_FS set):

    CC      init/version.o
    LD      init/built-in.o
    LD      vmlinux

  make: *** [vmlinux] Virhe 1

All those functions are in fs/proc/proc_sysctl.c, which has no CONFIG_
#define's in it, so the patch makes the compilation of that file to depend
on CONFIG_PROC_SYSCTL (the simplest choice).
