GitHub: fix matrix, package log files before upload

It turns out we were using the wrong matrix variable in the actual
make command and ran the same itest 6 times with no arguments, all
resulting in running the btcd test.

To avoid uploading too many files in individual requests, we zip them
first before uploading the zip itself.
