Since usign miscalculates SHA-512 digests for input sizes of exactly
64 + N * 128 + 110 or 64 + N * 128 + 111 bytes, we need to apply some
white space padding to avoid triggering the hashing edge case.
While usign itself has been fixed already, there is still many firmwares
in the wild which use broken usign versions to verify current package
indexes so we'll need to carry this workaround in the forseeable future.
