tests: add wierd sleep for libmount/context

I still don't understand why this helps to fix these tests on my system.
udevadm settle had no positive effect. Adding the sleeps before
"is_mounted" also didn't fixed that, that's amazing!?

Below the test log, very often seen on my system since a long time:
