[BUG] Deployed daemon is always unable to send report due to error while fetching partitions with FileNotFoundError

[Pyxsys]

Describe the bug

The daemon when deployed on a pi x64 environment, it always fails while fetching disk partition information.
It fails with error:
FileNotFoundError: [Errno 2] No such file or directory: '/dev/root'

To Reproduce

Steps to reproduce the behavior:

1. Deploy the daemon on a PiOS x64 environment
2. Start the daemon using celebid -s
3. Wait 30s
4. Open the daemon log
5. See error

Or

1. Deploy the daemon on a PiOS x64 environment
2. Run the tests via python3 -m unittest -v
3. See that the following tests fail:

• testFetchingPartition
• testAddingDiskUsageInfo

Expected behavior

The tests pass and the daemon is capable of fetching the partition information.

Device (please complete the following information):

• type: Raspberry Pi
• model: Raspberry Pi 3 Model B Plus Rev 1.3
• OS: Debian GNU/Linux 11 (bullseye)
• version: 11

This is known psutil issue.
giampaolo/psutil#1999
DataDog/datadog-agent#10544

Need to update required psutil version to 5.9.0
