Bug 723 - On some OS/distributions, hfaxd timezone handling is incorrect

On newer GLIBC, they *always* check /etc/localtime for timzone information
if TZ isn't set.  Older distros cache the localtime information.  If TZ isn't
set, we'll set it here before entering out chroot (where /etc/localtime
isn't available).
