Also add TAR_OPTIONS and TAR_CMD. Unfortunately, latest version of libsodium extracts to an additional libsodium-latest subfolder, which is unneccessary and removed by these options.

Functions from ed25519_core are needed for GNUnet to build.
Include them in the minimal build of libsodium so we don't need to
switch to the full build just for that.
