filter-repo: relax the definition of freshly packed

Browse Source 
transfer.unpackLimit defaults to 100, meaning that if less than 100
objects exist in the repository, git will automatically unpack the
objects to be loose as part of the clone operation.  So, if there are no
packs and less than 100 objects, consider the repo to be freshly packed
for purposes of our fresh clone sanity checks.
