[Tarantool-patches] [PATCH v1] test: fix flaky sql/func-recreate

["Alexander V. Tikhonov" <avtikhon@tarantool.org>]

Found that time limit in function used for testing in sql/func-recreate
test not enough for some time. Fiber set next is too near the time
limit. Decided to increase the time limit of the function, anyway it
checks its value at the test.

Close #4384
