Switch checksums from MD5 to BLAKE2
Historically, the MD5 checksums in our LFS files serve as a protection against broken downloads, or accidentally corrupted source files.
While the sources are nowadays downloaded via HTTPS, it make sense to beef up integrity protection for them, since transparently intercepting TLS is believed to be feasible for more powerful actors, and the state of the public PKI ecosystem is clearly not helping.
Therefore, this patch switches from MD5 to BLAKE2, updating all LFS files as well as make.sh to deal with this checksum algorithm. BLAKE2 is notably faster (and more secure) than SHA2, so the performance penalty introduced by this patch is negligible, if noticeable at all.
In preparation of this patch, the toolchain files currently used have been supplied with BLAKE2 checksums as well on https://source.ipfire.org/.
