fetch: make filter_options local to cmd_fetch()

The `struct list_objects_filter_options filter_options` variable used
in "builtin/fetch.c" to store the parsed filters specified by
`--filter=<filterspec>` is currently a static variable global to the
file.

As we are going to use it more in a following commit, it could become a
bit less easy to understand how it's managed.

To avoid that, let's make it clear that it's owned by cmd_fetch() by
moving its definition into that function and making it non-static.

This requires passing a pointer to it through the prepare_transport(),
do_fetch(), backfill_tags(), fetch_one_setup_partial(), and fetch_one()
functions, but it's quite straightforward.
