tests/rootless.sh: fixup for "update rt" test

Browse Source 
Without this, the test case fails with

> Writing 1000000 to /sys/fs/cgroup/cpu,cpuacct/runc-cgroups-integration-test/cpu.rt_period_us
> /tmp/bats-run-106836/bats.116418.src: line 548: /sys/fs/cgroup/cpu,cpuacct/runc-cgroups-integration-test/cpu.rt_period_us: Permission denied

Since we do not currently have a setup to test this, this went
unnoticed (can be seen in RHEL8 though).
