builtin/reflog: stop storing default reflog expiry dates globally

Browse Source 
When expiring reflog entries, it is possible to configure expiry dates
that depend on the name of the reflog. This requires us to store a
couple of different expiry dates:

  - The default expiry date for reflog entries that aren't otherwise
    specified.

  - The per-reflog expiry date.

  - The currently active set of expiry dates for a given reference.

While the last item is stored in `struct reflog_expire_options`, the
other items aren't, which makes it hard to reuse the structure in other
places.

Refactor the code so that the default expiry date is stored as part of
the structure. The per-reflog expiry dates will be adapted accordingly
in the subsequent commit.
