#### Problem

The event loop in JNI `IOThreadMain()` used to wait no more than ten
seconds on each iteration. This timeout was temporarily removed in
PR project-chip#6561.

#### Change overview

Add an explicit ten second timer.

Fixes project-chip#7756 _add a timer for sleepTime.tv_sec = 10; sleepTime.tv_usec = 0;_

#### Testing

How was this tested? (at least one bullet point required)
* If unit tests were added, how do they cover this issue?
* If unit tests existed, how were they fixed/modified to prevent this in future?
* If new unit tests are not added, why not?
* If integration tests were added, how do they verify this change?
* If new integration tests are not added, why not?
* If manually tested, what platforms controller and device platforms were manually tested, and how?
* If no testing is required, why not?
