The 'struct machine' represents the machine where the samples were/are being collected, and we also have a 'struct perf_env' with extra details about such machine, that we were collecting at 'perf.data' creation time but we also needed when no perf.data file is being used, such as in 'perf top'. So, get those structs closer together, as they provide a bigger picture of the sample's environment. In 'perf session', when the file argument is NULL, we can assume that the tool is sampling the running machine, so point machine->env to the global put in place in previous patches, while set it to the perf_header.env one when reading from a file. This paves the way for machine->env to be used in perf_event__preprocess_sample to populate addr_location.socket.
