platform: disable system agent on Zephyr builds

The system agent is not required with SOF Zephyr builds
as the Zephyr ll scheduler implementation can track DSP
load and print periodic status of the load and any observed
overruns in scheduling.

Disabling agent is beneficial as agent can create a lot of DMA traffic
when DMA trace is enabled. This happens if there is jitter in agent
execution, with delta slightly over the warning threshold. This can
itself worsen the scheduling variation and lead to actual problems.
