0.15.1 build fails with 'fatal error: unzip.h: No such file' on Archlinux

### Checklist

- [X] I have searched for [similar issues](https://github.com/isl-org/Open3D/issues).
- [X] For Python issues, I have tested with the [latest development wheel](http://www.open3d.org/docs/latest/getting_started.html#development-version-pip).
- [X] I have checked the [release documentation](http://www.open3d.org/docs/release/) and the [latest documentation](http://www.open3d.org/docs/latest/) (for `master` branch).

### Describe the issue

I was trying to build 0.15.1 on Archlinux however the build failed due to not finding unzip.h.
```
/home/zannzetsu/open3d/open3d/src/open3d/cpp/open3d/utility/ExtractZIP.cpp:34:10: fatal error: unzip.h: Nie ma takiego pliku ani katalogu
34 | #include

```
I know that Archlinux support is on a best effort basis, please consider looking into this in a spare moment.

### Steps to reproduce the bug

```python
git clone https://github.com/intel-isl/Open3D.git#tag=v0.15.1
cd open3d
git submodule update --init --recursive
mkdir -p build
cd build
find ../ -name "CMakeLists.txt" -exec sed -i 's/-Werror//g' {} \;
cmake .. \
-DBUILD_SHARED_LIBS=ON \
-DCMAKE_BUILD_TYPE=Release \
-DUSE_SYSTEM_GLEW=ON \
-DUSE_SYSTEM_GLFW=ON \
-DUSE_SYSTEM_JPEG=ON \
-DUSE_SYSTEM_PNG=ON \
-DUSE_SYSTEM_PYBIND11=ON
make -j 1
```
