libfuzzer integration doesn't seem to be working

I noticed the rust-fuzz/cargo-fuzz libfuzzer flags don't match the rust-fuzz/targets libfuzzer flags. I made the rust-fuzz/targets flags match the other ones, which got rid of the symbol not found errors, but I still hit the No such file or directory: ; exiting error. No idea where this is coming from.

Also the Rust + libfuzzer integration is working for me for other crates, just not this one.

Judging by "No such file or directory: ; exiting" it seems to be the same issue I ran into and fixed in #138. There I started to pass -max_total_time=0 instead of an empty string to make libFuzzer stop treating that argument as a directory.
