fixes memory leaks associated with the fuse option parser and curl handles

Browse Source 
Passing s3fs through valgrind revealed a few more memory leaks assocated with
the fuse option parser. We'll no longer directly return main from fuse_main().

In the event that s3fs_check_service failed, many of the curl handles were not
being cleaned up properly.
