No ARM32 support

[GoldenTK]

Hi,
I have a small raspberryPi 4 with code-server on it and I decided to use snowpack in my new project but when I tried to install esbuild I'm getting:

Unsupported platform: linux arm LE

My linux version:

Linux raspberrypi 5.4.75-v8+ #1367 SMP PREEMPT Mon Nov 9 15:11:16 GMT 2020 aarch64 GNU/Linux

Could you please add support for ARM64 platform? I think it's crucial to have support for ARM's.

There is already support for ARM64, but it appears installation is failing because os.arch() is returning arm rather than arm64 which esbuild expects. Is it possible you are accidentally using the 32-bit Node.js ARM binary? My understanding is that os.arch() actually returns the architecture of the Node.js process, not the OS CPU architecture.

Maybe esbuild should use a heuristic like https://github.com/feross/arch to determine the actual CPU architecture.

Hmm I just upgraded raspbian to 64bit version, maybe that's the case.
