ddns-scripts: Use parameter-based authentication for he.net

According to [1] Basic Auth seems to be broken since a while for he.net.
The documentation [2] is outdated, and still mentions Basic Auth, but
switching to parameter-based authentication seems to fix the issue.

It also bumps PKG_RELEASE in order to ensure a new version is packaged.
