Update dependency ejs to v2.7.4

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.

+//! This is a module that provides `malloc` and `free` for `libdeflate`.
+//! These implementations are compatible with the standard signatures
+//! but use Rust allocator instead of including libc one as well.
+//!
+//! Rust allocator APIs requires passing size and alignment to the
+//! `dealloc` function. This is different from C API, which only
+//! expects a pointer in `free` and expects allocators to take care of
+//! storing any necessary information elsewhere.
+//!
+//! In order to simulate C API, we allocate a `size_and_data_ptr`
+//! of size `sizeof(usize) + size` where `size` is the requested number
+//! of bytes. Then, we store `size` at the beginning of the allocated
+//! chunk (within those `sizeof(usize)` bytes) and return
+//! `data_ptr = size_and_data_ptr + sizeof(usize)` to the calleer:
+//!
+//! [`size`][...actual data]
+//! -^------------------ `size_and_data_ptr`
+//! ---------^---------- `data_ptr`
+//!
+//! Then, in `free`, the caller gives us `data_ptr`. We can subtract
+//! `sizeof(usize)` back and get the original `size_and_data_ptr`.
+//! At this point we can read `size` back and call the Rust `dealloc`
+//! for the whole allocated chunk.
+//!
+//! I've raised an upstream issue to hopefully make this easier in
