[myanmar-tools] Fix build by including libunwind.so.8 in lib (#2961)

The OSS-Fuzz builder and runner images have libunwind. Since
the OSS-Fuzz runner images aren't actually used to run fuzzers on
ClusterFuzz and are just actually used for testing(!) this passed
CI before even though it failed immediately on ClusterFuzz.
I've tested that with this fix, the fuzzer works on ClusterFuzz.
