Comment 8 for bug 1687454

LocutusOfBorg will cover the curl enablement on the current merge.
I tested from his ppa and it was ok.

Also tested the apache2 enablement - fine as well.
I not only dropped our disabling of http2 but also added a basic check to test it.
apache2 with changes is building in bionic-proposed now.

I'll report that autopkgtest to Debian now ...
