Commit c5b07d4 ("lib: fix beforeExit not working with -e") runs the
to-be-evaluated code at a later time than before because it switches
from `process.nextTick()` to `setImmediate()`.
It affects `-e 'process.on("message", ...)'` because there is now a
larger time gap between startup and attaching the event listener,
increasing the chances of missing early messages. I'm reasonably
sure `process.nextTick()` was also susceptible to that, only less
pronounced.
Avoid the problem altogether by evaluating the code synchronously.
Harmonizes the logic with `Module.runMain()` from lib/module.js
which also calls `process._tickCallback()` afterwards.
