New fuzzers (swim_proto_member_fuzzer and swim_proto_meta_fuzzer) uses
library core that requires libunwind. Unfortunately libunwind is not
available in environment where fuzzers run and it leads to bad build [1]:
BAD BUILD: /tmp/not-out/tmpq13wm8qb/swim_proto_member_fuzzer seems to
have either startup crash or exit:
/tmp/not-out/tmpq13wm8qb/swim_proto_member_fuzzer -rss_limit_mb=2560
-timeout=25 -seed=1337 -runs=4 < /dev/null
/tmp/not-out/tmpq13wm8qb/swim_proto_member_fuzzer: error while loading
shared libraries: libunwind-x86_64.so.8: cannot open shared object file:
No such file or directory
We don't want to fuzz backtrace-related source code in Tarantool, so
using libunwind has been disabled.
