[tz] [PATCH 2/5] tzselect.ksh: regions list to inclusive

[J William Piggott]

The regions list criteria was only based on
country. This caused, for example, all of
Australia to be listed under the regions for
Antarctica > Australia.

This commit requires both country and continent to
match for a region selection.
