commit 5b8956df3b3bc4593c0372703cfb07d75b4fc15e

    In test_establish_intro_wrong_purpose, use tt_i64_op on ssize_t
    
    Since ssize_t is signed and might be 64 bits, we should use
    tt_i64_op to make sure it's positive.  Otherwise, if it is negative,
    and we use tt_u64_op, we'll be treating it as a uint64_t, and we
    won't detect negative values.
    
    This fixes CID 1416338 and 1416339.  Bug not in any released Tor.
