Added forgotten directories zoneinfo/Antarctica and zoneinfo/Arctic.
Added forgotten directories zoneinfo/Antarctica and zoneinfo/Arctic.

The zoneinfo makefile doesn't follow the rules.  It builds everything
at install time.  It dpends on zic to create the directories.  zic
doesn't know about the weird 555 permissions specified in BSD.usr.dist,
so it creates the directories with nonstandard permissions.
