The cpluspluscheck script wraps our headers in `extern "C"`. This disables name mangling, which is necessary for the C++ templates in system ICU headers. cpluspluscheck thus fails when the build is configured with ICU (the default). CI worked around this by disabling ICU, but let's make it work so others can run the script. We can specify we only want the C APIs by defining U_SHOW_CPLUSPLUS_API to be 0 in pg_locale.h. Extensions that want the C++ APIs can include ICU headers separately before including PostgreSQL headers.
