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

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).
