[CentOS-docs] [Propose] Chroot vsftpd with non-system users

[Sunry Chen]

The proposed subject of Wiki contribution:
Chroot vsftpd with non-system users

The proposed location of Wiki contribution:
http://wiki.centos.org/HowTos/Chroot_Vsftpd_with_non-system_users

I propose this Wiki to give user choice that they can select whether
virtual users
and system account coexist in vsftpd system.

The shell file vsftpd_virtual_config.sh should also adjust to make
this function work.

It works for me to put below two lines ahead of the original
/etc/pam.d/vsftpd file:
auth    sufficient  pam_userdb.so db=/etc/vsftpd/accounts
account sufficient  pam_userdb.so db=/etc/vsftpd/accounts
