Make win32tzlist.pl checkable again

adunstan · adunstan · commit 8ddf9c1dc020 · 2023-12-22T13:56:27.000Z
Commit 1301c80 removed some infrastructure needed to check windows-oriented perl scripts. It also removed most such scripts, but this one was left over. We repair the damage by making Win32::Registry a conditional requirement that is only loaded on Windows. With this change `perl -cw win32tzlist.pl` once again passes on non-Windows machines.
