The order was non-deterministic before, and just happened to work for
sync023.py as it was written. Ensure there is some sort of predictable
ordering.

As reported in FS#20221, we don't always do the right thing when installing
a group and using the --needed option. This was due to the code pulling
packages based on what was already in the transaction's add list, but
completely ignoring the fact that we may have already seen and skipped this
same package in an earlier repository.
Add a list to the private _alpm_sync_pkg() function that allows us to have
this extra information so we don't mistakenly downgrade a package when using
--needed.

The first step for resolving FS#20221. sync023 is the case from the bug
report; sync022 is already working fine but we have no tests at all that
test the --needed option in any form.
