meta-nuvoton: npcm7xx-bootblock: version the download name

Rename the bootblock image as it is being downloaded to contain the
current version string.

Currently, all versions of the bootblock are downloaded with the same
file name. This breaks mirroring and reproducibility of builds since
multiple versions can't be kept in a mirror at once.
