Support for OpenBSD/adJ

[vtamara]

💡 Feature description

Being able to use wasm-pack on OpenBSD/adJ.

It is important for example to have rollup on that platform see rollup/rollup#5478

💻 Basic example

Now using OpenBSD/adJ 7.4 that has rustc 1.72.1 and node 18.18.0:

% curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
wasm-pack-init: no precompiled binaries available for OS: OpenBSD

However it is possible to compile with:

% cargo install wasm-pack
...
% cargo install --locked wasm-pack
...
   Installed package `wasm-pack v0.12.1` (executable `wasm-pack`)
warning: be sure to add `/home/vtamara/.cargo/bin` to your PATH to be able to run the installed binaries

% ~/.cargo/bin/wasm-pack
