use sha512sum to check downloads, not sha1sum 

sha-1 has known collision issues, which may not be readily
exploitable yet (in our context), but we should ideally use
a more secure method for checking file integrity.

therefore, use sha-2 (sha512sum) for checking files. this is
slower than sha-1, but checksum verification is only a minor
part of what lbmk does, so the overall effect on build times
is quite negligible.

# If you want to make additions, try to add a backup url for download links and
# list hashes as sha1 sums.
# NOTE: this file now defines checksums as sha512 (of the sha-2 family),
# where previously we used 160-bit SHA-1 algorithm; SHA-1 is not secure,
# having demonstrated collisions, so we have switched to using sha512sum
