Requires a downgraded libffi

This originated with https://github.com/dbcli/mycli/issues/1008#issuecomment-973446530.

On arch linux the standard libffi package no longer includes libffi.so.7. Would it be possible to update pyperclip to use libffi.so.8?

Nevermind. I think this was all due to an out of date python/pip. Nothing to see here...
