Subject: [PATCH] net: explicitly include std::array

On boost 1.81 std::array is no longer included by default and
causes a compile error on net_processing.cpp:

macOS with apple clang 14.0:

  CXX      libdogecoin_server_a-net_processing.o
net_processing.cpp:1112:47: error: implicit instantiation of undefined template 'std::array<std::pair<unsigned long long, CNode *>, 2>'
    std::array<std::pair<uint64_t, CNode*>,2> best{{{0, nullptr}, {0, nullptr}}};

debian:exprimental with gcc 12.1:

net_processing.cpp: In function 'void RelayAddress(const CAddress&, bool, CConnman&)':
net_processing.cpp:1112:47: error: variable 'std::array<std::pair<long unsigned int, CNode*>, 2> best' has initializer but incomplete type
 1112 |     std::array<std::pair<uint64_t, CNode*>,2> best{{{0, nullptr}, {0, nullptr}}};
      |

this commit fixes the problem by explicitly including <array>.
