Subject: configuration: Add missing #include <array>

As user "DaOfficialRolex" on GitHub pointed out:

This is needed to allow for APT on iOS to compile correctly. If not included the two following errors happen while compiling APT.

~/apt/apt-pkg/contrib/configuration.cc:900:44: error: constexpr variable cannot have non-literal type 'const std::array<APT::StringView, 3>'
         constexpr std::array<APT::StringView, 3> magicComments { "clear"_sv, "include"_sv, "x-apt-configure-index"_sv };
                                                  ^
