[PATCH] Git.pm: Fix internal git_command_bidi_pipe() users

[Petr Baudis <pasky@suse.cz>]

The hash_and_insert_object() and cat_blob() helpers were using
an incorrect slice-from-ref Perl syntax. This patch fixes that up
in the _close_*() helpers and make the _open_*() helpers use the
same syntax for consistnecy.

  Wow, the command_bidi_pipe API really is dirty. Of course, it is
my fault as anyone's since I didn't get around to review the patches
introducing it.
