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.

We need to pass options with "-fsanitize=fuzzer" two times
(in cmake/profile.cmake and test/fuzz/CMakeLists.txt) because:

- cmake/profile.cmake is for project source files,
  -fsanitize=fuzzer-no-link option allows to instrument project source
  files for fuzzing, but LibFuzzer will not replace main() in these
  files.

- test/fuzz/CMakeLists.txt uses -fsanitize=fuzzer and not
  -fsanitize=fuzzer-no-link because we want to add automatically
  generated main() for each fuzzer.
