[PATCH 01/21] gc: use the_repository less often

["Derrick Stolee via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>

In a later change, we will consume several static methods in
builtin/gc.c for another builtin. Before doing so, let's clean up some
uses of the_repository. These specifically are centered around accesses
to the packed_git list.
