debian zoneinfo link fix

[Attila Lendvai]

hi,


> Unfortunately, on Debian 7 at least, /usr/share/zoneinfo/ contains a symlink “localtime” which points back to /etc/localtime.

thanks for the patch!

have you considered simply adding :follow-symlinks nil to the
cl-fad:walk-directory call? that seems to me like a more
straightforward fix.
