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.

the RTC Audio processing component required to have both left and right
channel as reference.
xtensa-build-zephyr.py: clone zephyr with --depth 5
This restores the performance of the original shell script and makes a
big difference in CI. CI clones over and over again whereas developers
clone rarely and can run a simple git fetch --unshallow.
Don't use --depth 0 to provide more context in the logs and also make it
more obvious that this is a shallow clone and not just git log -n 1.
