Fix astyle indentation of #include inside #ifdef in unit-items-cpp17.cpp

This repo's astyle style keeps preprocessor directives at column 0
even inside #ifdef blocks. The new tests/src/unit-items-cpp17.cpp
had its #include <map>/#include <string> indented, which made the
'check' CI job's amalgamation/formatting diff non-empty and failed
the aggregate check.
