base-passwd: install passwd and group atomically 

Fixed the race issue:
util-macros.do_package failed: 'getpwnam(): name not found: root'

The error happens when there is a half etc/passwd, fixed by:
$ install usr/share/base-passwd/passwd.master etc/passwd.master
$ mv etc/passwd.master etc/passwd

The "mv" is atomic which will fix this problem.
