mix hex.registry build crashes with some tarballs

[Mark Geib]

Testing self hosting of registry fails with some packages I try to add, also tried packages downloaded from hex.pm. Other tarballs work fine as you can see. My tarball is built with "rebar3 publish" command.

$mix hex.package fetch rebar3_hex 6.10.3
rebar3_hex v6.10.3 downloaded to /home/name/os-git/hex/rebar3_hex-6.10.3.tar
$cp rebar3_hex-6.10.3.tar public/tarballs/.
$ mix hex.registry build public --name=acme --private-key=private_key.pem
