Do not build with gcc-5.

We build with gcc-5 because of zimSplit using ofstream.swap method.
Latest version of zimSplit doesn't use it anymore so let's compile
everything with default gcc.

See openzim/zim-tools@a959609839

We also explicitly set the list of package to install per job, so
less packages are installed.
