Ahmed Ibrahim 6052558a01 Stabilize RMCP pid file cleanup test (#13881)
## What changed
- The pid-file cleanup test now keeps polling when the pid file exists
but is still empty.
- Assertions only proceed once the wrapper has actually written the
child pid.

## Why this fixes the flake
- File creation and pid writing are not atomic as one logical action
from the test’s point of view.
- The previous test sometimes won the race and read the file in the tiny
window after creation but before the pid bytes were flushed.
- Treating “empty file” as “not ready yet” synchronizes the test on the
real event we need: the wrapper has finished publishing the child pid.

## Scope
- Test-only change.
