opensbi: update tarball hash compressed by the zstd 1.5.7

The source code tarball packaged by the zstd 1.5.6 was accidentally
lost from OpenWrt mirror https://sources.cdn.openwrt.org/ and
https://sources.openwrt.org/. Now we have to use the new tarball
packaged by the zstd 1.5.7 to fix the GitHub CI warning.
