[PATCH v1] configs: socfpga: stratix10: Disable mkeficapsule tool build

[NG, BOON KHAI]

Hi Tom,

> Why / how is this failing to compile?

When compile without disabling the mkeficapsule tool
will hit into this error:

tools/mkeficapsule.c:20:10: fatal error: gnutls/gnutls.h: No such file or directory
 #include <gnutls/gnutls.h>
          ^~~~~~~~~~~~~~~~~
compilation terminated.
make[1]: *** [scripts/Makefile.host:113: tools/mkeficapsule.o] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:2201: tools] Error 2

We are not using that tools, I think we should just disable it.

Regards,
Boon Khai.
