Since upstream commit 0c716a157be460006a4b762625de329b5e36dbf9 (first
release: v2026.07) mkeficapsule supports PKCS#11 keys, and in turn
requires GnuTLS with PKCS#11 support.
Without it, building mkeficapsule for the target fails:

collect2: error: ld returned 1 exit status
The error can be reproduced using "utils/test-pkg -c" with the
following config:
BR2_PACKAGE_UBOOT_TOOLS=y
BR2_PACKAGE_UBOOT_TOOLS_MKEFICAPSULE=y
For host-uboot-tools this was solved in Buildroot commit
6597563da7 "package/gnutls: add host
support for pkcs11" by unconditionally enabling PKCS#11 support for
host-gnutls. For the target a more fine-grained approach is desirable,
so instead select BR2_PACKAGE_P11_KIT if
BR2_PACKAGE_UBOOT_TOOLS_MKEFICAPSULE=y and propagate dependencies.
