repack: only unpack-unreachable if we are deleting redundant packs 

The -A option calls pack-objects with the --unpack-unreachable option so
that the unreachable objects in local packs are left in the local object
store loose. But if the -d option to repack was _not_ used, then these
unpacked loose objects are redundant and unnecessary.

Update tests in t7701.
