polybarFull: fix gcc15 build by bumping i3ipcpp to C++17 

The i3ipcpp submodule (used when i3Support=true) forces -std=c++11,
but the jsoncpp library is compiled with C++17 (JSONCPP_HAS_STRING_VIEW=1).
This causes an ABI mismatch: i3ipcpp resolves operator[](const char*) but
the jsoncpp library only exports operator[](std::string_view), resulting in
undefined references at link time.

Fix by changing i3ipcpp's compile standard from C++11 to C++17 to match
the jsoncpp ABI. Polybar itself already uses C++17.
