Compilation error when building with the seccomp feature

Hi

The debian build system runs unit tests for all features, and the seccomp feature seems to be broken.

Truncated example:
```
$ cargo test --features seccomp
Updating crates.io index
Compiling alloc-no-stdlib v2.0.3
Compiling alloc-stdlib v0.2.1
Compiling brotli-decompressor v2.3.2 (/tmp/rust-brotli-decompressor)
error[E0061]: this function takes 3 arguments but 4 arguments were supplied
--> src/bin/integration_tests.rs:447:11

447 | match super::decompress(&mut input, &mut output, input_buffer_size, Vec::new()) {
| ^^^^^^^^^^^^^^^^^ ---------- ----------- ----------------- ---------- supplied 4 arguments
| |
| expected 3 arguments
|
note: function defined here
--> src/bin/brotli-decompressor.rs:215:8
|
215 | pub fn decompress(r: &mut InputType,
| ^^^^^^^^^^ -----------------
216 | mut w: &mut OutputType,
| ----------------------
217 | buffer_size: usize)
| ------------------

```

Should I maybe patch that feature out of the package when building it, or is it important for something?
