Revert "Avoid excessive polling of universal variable file"

Browse Source 
This reverts commit b56b230076.
which somehow made us miss repaints on uvar notifications.

The commit was a workaround for a polling bug which was later properly
fixed by 7c5b8b855 ("Use the uvar notifier pipe timestamp to avoid
excessive polling"), so it's no longer necessary.

Add a system test. If I had a better understanding of the bug I could
probably write a better test.

Fixes #8088
