Re-enable the fuzzing tests
The fuzzing tests were temporarily disabled when the build system has been converted to automake. This commit restores the functionality to run the fuzzing tests as part of the `make check`. When the afl or libfuzzer is enabled via ./configure, it uses a custom LOG_DRIVER (fuzz/<fuzzer.sh>). Currently only libfuzzer.sh has been implemented that runs each fuzz test for 5 seconds each.
