set_passwords: support for FreeBSD (#46)

Allow setting of user passwords on FreeBSD

The www/chpasswd utility which we depended on for FreeBSD installations
does *not* do the same thing as the equally named Linux utility.

For FreeBSD, we now use the pw(8) utility (which can only process one
user at a time)

Additionally, we abstract expire passwd into a function, and override it
in the FreeBSD distro class.
