chore: set UV_USE_IO_URING=0 on npm builds

There's currently a bad interaction between the nodejs version in the
archives and the kernel, causing an infinite hang during 'npm install':
- npm/cli#4028
- amazonlinux/amazon-linux-2023#856

For now we need to disable libuv's use of io_uring because this hanging wrecks
spread runs; this should be able to be reverted in a few months
(as of April 2025).
