Coin hitting its own 3h time-out on Android

This attempted integration timed out after 3 hours. I can't see anything obviously stuck, just the whole process of running tests takes a long time, possibly due to running on VMs that weren't getting enough time-slices. There is one pause of several minutes, from 22:39:09's computation of the test timeout (which appears to be when the three hour timer started) to 22:43:24's report of executing the first test; this may well just be the time that test took to run. Other than that, the three hours do appear to have simply been taken up by running tests at a steady rate, with no obviously visible long delays.

Possible remedies:

• Replace the wall-clock time-out with a system-time time-out (so when the process has actually used 3h of CPU-time, not counting time it was swapped out to let some other process run (other than its children) or time when its VM wasn't getting run).
• Increase the time-out, at least for this platform.

(I note, in passing, that "Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0." We should probably fix that, too.)
