spidermonkey_91: fix build with python311

[devusb]

Description of changes

The recent change of python3 to be python311 breaks the build of spidermonkey_91 due to its use of a deprecated file mode. Although spidermonkey_91 is EOL, it's still required by couchdb3 -- this PR adds a patch borrowed from Fedora to fix the file modes and allow building with python311.

ZHF: #265948

@marius851000 mind marking with an approve if it worked for you?

Approval? Doesn't that require some specific permission that I don't have?
