[Tarantool-patches] [PATCH 4/4] test: integrate with OSS Fuzz

[sergeyb@tarantool.org]

From: Sergey Bronnikov <sergeyb@tarantool.org>

To run Tarantool fuzzers on OSS Fuzz infrastructure it is needed to pass
library $LIB_FUZZING_ENGINE to linker and use external CFLAGS and CXXFLAGS.
Full description how to integrate with OSS Fuzz is in [1] and [2].

Patch to OSS Fuzz repository [2] is ready to merge.

1. https://google.github.io/oss-fuzz/getting-started/new-project-guide/
2. https://google.github.io/oss-fuzz/advanced-topics/ideal-integration/
3. https://github.com/google/oss-fuzz/pull/4723

Closes #1809
