configs/zynqmp_kria_kv260_defconfig: use CONFIG_MULTI_DTB_FIT

When using the buildroot compiler, it builds the u-boot.itb immediately
after building the fit-dtb.blob.  This causes a build failure when using
the CONFIG_MULTI_DTB_FIT build configuration.  This patch adds the necessary
dependency to guarantee that the fit-dtb.blob has finished building before
trying to build the u-boot.itb.

+Subject: [PATCH v1 1/1] makefile: add multi_dtb_fit dep
+
+With certain gcc compilers, the u-boot.itb is built immediately after dtb
+generation.  If CONFIG_MULTI_DTB_FIT is used, it is possible that the
+fit-dtb.blob is not finished in time.
+
+This patch adds a necessary dependency to guarantee that the fit-dtb.blob
+is built before attempting to build the u-boot.itb.
