package/dillo: move to github

Fixes http://autobuild.buildroot.net/results/9c33099772398ab592bf38c2f4c56c2594594695/

The tarball is no longer available on dillo.org, but has been uploaded to
github so use that instead:

https://github.com/dillo-browser/dillo/releases/tag/v3.0.5

Also adjust the URL in the help text to the new location, which states:

"The domain dillo.org is no longer under control of Dillo developers."
