fix(streamer): zip64 should work on 32-bit now

Summary

This should work again now that DeepDiver1975/PHPZipStreamer#11 is merged. We've already bumped v28-v30 up to >2.0.1 of ZipStreamer (in nextcloud/3rdparty#1673 and nextcloud/3rdparty#1863).

Untested since I no longer have a 32-bit environment set up for testing.

Came up while looking into nextcloud/files_zip#200.

Maybe @bcutter feels like testing this change too for the standard built-in zip mechanism? :)

To test:

• source needs to consist of >4GB worth of files (or) >65536 files.

TODO

• ...

Tested with a folder of 5.38 GB in total.

1. Without the patch: took quite some time (5 minutes on a Pi 4 with external SSD), but worked without an issue. During generation there was a 0 KB "place holder" zip file.
   

2. Because of 1 I did not try to use it with the patched Streamer.php file.

Please note I have patched the file 20 minutes before but reverted that changes, see nextcloud/files_zip#200 (comment) for details.

1. Pi 4

The Pi 4 supports 64bit OS and php afaik

[bcutter]

Sure. Back in the days it did not and a migration takes a lot of time - so it still runs on a 32 bit OS. Great you asked.

https://github.com/nextcloud/server/actions/runs/11668606807 I can run 32bit CI on this branch, but it seems there is no test for the streamer.
I’m not sure it’s worth it to add a test with >4GB files, it will eat up a lot of CI resources.

Can someone with a 32bit setup test locally instead?

Or @joshtrichards if you push a test to this branch I can run the CI again and afterwards we remove or comment out the test.
