tests: avoid infinite loop in dd failure edge case

Browse Source 
* tests/tee/tee.sh: If dd failed, then tee would spin
writing to the fifo forever, so add a timeout protection.
This was noticed with `export LD_PRELOAD=libasan.so.8`
with a non ASAN build, which induced a failure in dd invocations.
