Rename and update tests for UNIX-specific functionality
Renamed `msg_nowin_test.go` to `msg_unix_test.go` to better reflect its purpose. Updated the file attachment test to use `/dev/mem` for Unix environments instead of a temporary file with restricted permissions, ensuring compatibility with continuous integration environments.
