Problem with go runtime module

@antoniocapizzi95 can you share the build command you use for your Go plugin code? The error “different version of package internal/cpu” always occurs when the -trimpath flag is not used to make sure the built code is filesystem independent or when you have your Go toolchain at a different version to the version that Nakama was built for. Right now the v2.11.1 release uses Go 1.14.1 and not the newest Go 1.14.2 release yet.
