nlohmann JSON: don't use std::snprintf

Browse Source 
libintl.h defines a preprocessor define for `snprintf` with the
content of `libintl_snprintf` if the C library isn't GNU's
glibc. Therefore `std::snprintf` actually becomes
`std::libintl_snprintf` which doesn't exist. This affects e.g. mingw
and macOS.
