🧑‍🌾 Nightly coverage job failing in subprocess run

[Crola1702]

Rolling nightly coverage job is failing to generate coverage reports, killing node ssh-agent and generating a lot of java exceptions due to the closed connection.

This problem is happening since the change to use Noble by default on this job.

Reference builds:

• https://ci.ros2.org/job/nightly_linux_coverage/2345/
• https://ci.ros2.org/job/nightly_linux_coverage/2344/
• https://ci.ros2.org/job/nightly_linux_coverage/2343/

The failure is thrown in:

ci/ros2_batch_job/__main__.py

Lines 295 to 298 in b6cd705

	outfile = os.path.join(args.buildspace, 'coverage.xml')
	print('Writing coverage.xml report at path {}'.format(outfile))
	cmd = ['lcov_cobertura', coverage_file, '--output', outfile]
	subprocess.run(cmd, check=True)

and it's the following:
