Delete files with no licenses

[Girgias]

@derickr are any of these files used on the build machine?

At least one is, I can't guarantee the others, so I would be reluctant to just remove them.

$ grep -r fetch-ch
rsync.php.net/cronjobs.docbuilder:10 9 * * 5 php /home/docbuilder/phpdoc-all/doc-base/scripts/fetch-chms.php
docs/README.rsync:CHMS are copied from oti1.php.net with the phpdoc/doc-base/trunk/scripts/fetch-chms.php script

And you can't delete this one: scripts/gen-phpdoc-tz-list.php — it is used when the tz-data is updated. I wrote it, so pick what licence makes sense for it: https://github.com/derickr/timelib/blob/master/zones/Makefile#L69
