Bug#1057689: minetest: calls home for upstream version check

[David Heidelberg]

Hello!

as a workaround you can set empty `update_information_url` in 
`~/.minetest/minetest.conf`.

For Debian developer maintaining minetest, this can be patched in 
`src/defaultsettings.cpp` same way by setting it to empty string.

Please, consider this message also as a request to bump minetest up to 
5.8.0 version.

Thank you!
