Makefile: Add a rule to build core module on x86_64 only

core module is currently supported on x86_64. Trying to
build it on powerpc, triggers build failure:

make[3]: Entering directory '/root/kernel/linux'
  CC [M]  /root/upstream/kpatch/kmod/core/core.o
/root/upstream/kpatch/kmod/core/core.c:48:28: fatal error: asm/stacktrace.h: No such file or directory
 #include <asm/stacktrace.h>
                            ^
compilation terminated.
scripts/Makefile.build:294: recipe for target '/root/upstream/kpatch/kmod/core/core.o' failed
make[4]: *** [/root/upstream/kpatch/kmod/core/core.o] Error 1

Add a Makefile rule to build it, only on x86.
