[system_health][Dell 9332] test_system_health fails since thermal_policy.json is missing for Dell platforms

[tjchadaga]

Description

thermal_policy.json file is missing for Dell platforms. This is causing test_system_health to fail at test_device_checker

Steps to reproduce the issue:

1. Execute test_system_health.py::test_device_checker

Describe the results you received:

Test case fails and throws the below error: "mv: cannot stat '/usr/share/sonic/device/x86_64-dellemc_z9332f_d1508-r0/thermal_policy.json': No such file or directory"

@gechiang , @tjchadaga Thermal control is done by BMC in DellEMC Z9332f platform. There is no need to implement thermal_policy.json for this platform and the test script may have to be changed to ignore the thermal_policy.
