Introduce a separate TU for utility functions util.c. Add a function exec_cmd to simplify execution of system commands with error handling. While at it, suppress a warning about unused result when executing a shell command. As we only display the command's output we do not care about the exit code. This fixes Debian bug #398989[0] [0]: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=398989
