OHOS CI: Install the required hitrace-bench version (#37915)

OHOS CI: Install the required hitrace-bench version if it is not already
installed. This allows us to see the hitrace-bench version in the commit
history without it being reinstalled on CI all the time.
This does not change the version of hitrace-bench in this PR.

This needs another update of the docker images to get the correct build
tools installed.

Succesful run:
https://github.com/Narfinger/servo/actions/runs/16115943664/job/45469959328
And here a run where it installs the given version:
https://github.com/Narfinger/servo/actions/runs/16116949656/job/45473231784
Testing: Tested on CI.
