[PATCH v2] configs: socfpga: stratix10: Disable mkeficapsule tool build

[Boon Khai Ng]

mkeficapsule tool is automatically enabled when EFI_LOADER is selected,
which introduces a host dependency on libgnutls.

This causes build failures in minimal toolchain environments where
gnutls headers are not installed.

Stratix10 SoCFPGA platforms do not use UEFI capsule update workflows
and therefore do not require mkeficapsule.

Disable CONFIG_TOOLS_MKEFICAPSULE in Stratix10 defconfigs to:
(1) avoid unintended host dependency on gnutls,
(2) reflect actual platform capability, and
(3) prevent tool build failures in minimal environments.

This is intended as an interim fix; a proper Kconfig refinement to
only enable mkeficapsule when capsule update support is actually used
is being discussed with EFI maintainers.

Changelog:
v2:
- Update commit message to clarify root cause of build failure
  (missing gnutls/gnutls.h when mkeficapsule is enabled by EFI_LOADER).
- Clarify that Stratix10 SoCFPGA platforms do not use UEFI capsule
  update workflows, so mkeficapsule is not required for these boards.
- Explicitly state this change is intended as an interim workaround
  to avoid unintended host dependency on libgnutls in minimal builds.
- Note that a longer-term fix should refine Kconfig logic to enable
  mkeficapsule only for platforms that actually support capsule updates.
