Add AFL_MAP_SIZE in run_fuzzer
Otherwise get errors like these for libsass.
[+] All right - fork server is up.
[-] PROGRAM ABORT : AFL_MAP_SIZE is not set and fuzzing target reports that the required size is very large. Solution: Run the fuzzing target stand-alone with the environment variable AFL_DEBUG=1 set and set the value for __afl_final_loc in the AFL_MAP_SIZE environment variable for afl-fuzz.
Location : report_error_and_exit(), src/afl-forkserver.c:321
