test: bump the TEST-47 sleeps once again Several recent failed runs show that the test is still racy in two ways: 1) Sometimes it takes a while before the PID file is created, leading to: ``` [ 10.950540] testsuite-47.sh[308]: ++ cat /leakedtestpid [ 10.959712] testsuite-47.sh[308]: cat: /leakedtestpid: No such file or directory [ 10.959824] testsuite-47.sh[298]: + leaked_pid= ``` 2) Again, sometimes we check the leaked PID before the unit is actually stopped, leading to a false negative: ``` [ 18.099599] testsuite-47.sh[346]: ++ cat /leakedtestpid [ 18.116462] testsuite-47.sh[333]: + leaked_pid=342 [ 18.117101] testsuite-47.sh[333]: + systemctl stop testsuite-47-repro ...
