Exclude thermald thermal management for Dell Optiplex XE4

[Kai-Chuan Hsieh]

[ Impact ]

 * Dell would like to disable thermald thermal management on Dell OptiPlex XE4 for 20.04

 * The reason is that the thermald on focal is too old to support the thermal policy configured in the BIOS
, it leads the problem in lp:2064083. However, the platform can rely on EC to do the thermal management, so that it can omit the issue if thermald is inactive on the platform.

[ Test Plan ]

 * Install the package on the target OptiPlex XE4 platform, product sku 0ACB

 * Run $ systemctl status thermald

 * The status should be inactive

 * Run $ systemctl status thermald on other platforms, the status should be as what it was.

[ Where problems could occur ]

 * The change only takes effect on the target platform, the other platforms should work as what it was. If other platforms dmi reports the same pattern in sys_vendor and product_sku, the thermald will stop working too.

[ Other Info ]

 * The thermald version after jammy can support the table configured in the BIOS correctly, so there is no need to apply the patch to the codename >= 22.04.
