[Tarantool-patches] [PATCH luajit v2] test: fix flaky OOM error frame test

[Maksim Kokryashkin via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

This test could do allocation outside of the protected frame,
which could result in an uncaught OOM and test failure. This
patch adds extra `collectgarbage` calls to the test to avoid
such situations.
