configs/hifive_unmatched: add missing uboot custom hash file
Commit [1] introduced the hifive_unmatched_defconfig with
BR2_DOWNLOAD_FORCE_CHECK_HASH enabled and with custom hash files.
But it forgot to add the custom hash for uboot. It was not detected
at that time because the U-Boot version was the same as the default
"latest" version and was providing its hash.
This defconfig fails to build since the default "latest" was bumped
in commit [2].
This commit fixes the issue by adding the missing uboot hash.
