[oe] [PATCH meta-networking v2] proftpd: use /bin/false as the login shell and add home-dir

[rongqing.li at windriver.com]

From: Roy Li <rongqing.li at windriver.com>

Use /bin/false as the login shell, just like what Ubuntu does,
otherwise there might be secure issue; add /var/lib/ftp as user
ftp home-dir.
