[PATCH] clone: Skip pack-*.keep files when cloning locally

[Jens Lindstrom <jl@opera.com>]

The pack-*.keep files are temporary, and serve no purpose in the
clone.  They would probably also never be deleted from the clone if
copied, since the process that created them only expects to have to
delete them from the original repository.

Worse, though, they are created with access bits 0600, so if the
user trying to clone the repository is different from the user that
caused the pack-*.keep file to be created, the clone will likely
fail due to not being allowed to read (and thus copy) the file in
the first place.
