tzdata: Simplify code removing not used cases

We shouldn't have an use-case where we'd use 'FUBAR' timezone so
instead of adding postinst handling for this use case we handle it at
install time and keep the Universal as fallback if user did something
wrong.

This also ensure the /etc/localtime file is kept as a symbolic link.
This will make timezone not available when /usr is in separated
partition (and not mounted) however the applications ought to fallback
to GMT timezone in this case and when /usr is made availble timezone
will work fine.
