Now that kvazaar is available in Debian (https://packages.debian.org/source/sid/kvazaar), I want to enable the kvazaar plugin there.

Unfortunately the encode tests are failing now:
```
./tests/encode.cc:154: FAILED:
  REQUIRE( ispe_width == expected_ispe_width )
with expansion:
  128 == 122
```

If I remove the `libheif-kvazaar.so` file, the tests are passing.

@farindk not sure how to fix this properly for all cases (with / without kvazaar).
