[PATCH v4 04/13] pack-objects: use rev.filter when possible

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <derrickstolee@github.com>

In builtin/pack-objects.c, we use a 'filter_options' global to populate
the --filter=<X> argument. The previous change created a pointer to a
filter option in 'struct rev_info', so we can use that pointer here as a
start to simplifying some usage of object filters.
