find_cfg_ent() allocates a struct reflog_expire_entry_option via
FLEX_ALLOC_MEM and inserts it into a linked list in the
reflog_expire_options structure. The entries in this list are never
freed, resulting in a leak in cmd_reflog_expire and the gc reflog expire
maintenance task:

Direct leak of 39 byte(s) in 1 object(s) allocated from:

Close this leak by adding a reflog_clear_expire_config() function which
iterates the linked list and frees its elements. Call it upon exit of
cmd_reflog_expire() and reflog_expire_condition().

Add a basic test which covers this leak. While at it, cover the
functionality from commit commit 3cb22b8 (Per-ref reflog expiry
configuration, 2008-06-15). We've had this support for years, but lacked
any tests.
