gnu: vm: Create valid /etc/shadow and /etc/passwd.
* gnu/system/vm.scm (/etc/passwd): Rename to... (passwd-file): ... this. Add 'shadow?' keyword parameter. Change format of ACCOUNTS, and fix CONTENTS. (example2): Adjust accordingly. Create both /etc/shadow and /etc/passwd, the latter being used by getpwnam(3) & co. when nscd is not running.
