get.sh: use the same directory map as --mirror

Don't hardcode the cache directory, and don't store
remotes anymore. This change retains compatibility
in practice, with the older directory location, because
it's extremely unlikely that newly generated locations
would conflict with old ones.

With this new change, non-mirror git clone caches are
now done twice; one directory per remote, rather than
one directory with two remotes.

This is just inherently much more reliable.
