We've been running each Make command in a single thread, resulting in fairly slow builds for C++ codecs. This change instead runs all `make` invocations with `-j` defaulting to number of cores (retrieved via `nproc`). On my machine Docker uses a VM configured to 4 cores out of 8 available. This change brings total build time for C++ codecs down from 10m28s to 7m5s (~3.5 minutes difference). Note (1): I've converted imagequant builds to use built-in `make` as well to leverage this parallelisation and future-proof build script. Note (2): we don't need to do the same for Rust, since Cargo parallelises builds by default.
