Fix missed updates of alias table when INTROSPECTION is on

In src/afl-fuzz.c `prev_queued_items` is used to decide whether the alias table should be recreated through the comparison with `afl->queued_items`.

However, this variable is also updated to `afl->queued_items` when INTROSPECTION is enabled and the `fuzz_one` appends seeds.

Due to the update of `prev_queued_items` when INTROSPECTION is on, alias table may not be recreated when it actually should be.

This can lead to potential heap buffer-overflow in `select_next_queue_entry` due to the lack of `afl_realloc` called in `create_alias_table`.

This patch fixes this bug by utilizing another variable for the INTROSPECTION part like other variables such as `prev_saved_tmouts`.
