Bug: fsmonitor--daemon doesn't pick up submodule changes

[Benedek Kozma <cyberbeni@gmail.com>]

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)
git status
cd submodule
git checkout origin/HEAD
cd ..
git status

What did you expect to happen? (Expected behavior)
the second git status showing that a submodule changed

What happened instead? (Actual behavior)
second git status also shows up to date

What's different between what you expected and what actually happened?

Anything else you want to add:
I have core.fsmonitor set to true in ~/.gitconfig
If I run `git status` with git version 2.32.1 then 2.36.1 will also
correctly report the submodule as changed after the next git status
(because I don't have an fsmonitor script named true, using git 2.32.1
will reset my cache)

Please review the rest of the bug report below.
