Fix setTimeout with node:util.promisify

[pfgithub]

Fixes #15201, alternative for #15203

This regressed in 1.1.27 (specifically commit https://github.com/oven-sh/bun/commit/76c4145f0e95b27610e37130c3457eff7e2e95fb) and didn't get caught because it still worked if "node:timers" was imported in the same file.

This is still slightly different from node, in node setTimeout[Symbol.for("nodejs.util.promisify.custom")] will return a function without any imports, but with this PR in bun it requires require("util") before the custom promisify is defined on setTimeout.
