[Buildroot] [git commit] configs/hifive_unmatched: add missing uboot custom hash file

[Julien Olivain]

commit: https://git.buildroot.net/buildroot/commit/?id=7d890426bcef037a5d09624913d9c22d91ed9c94
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
