[Bug 2119043] [NEW] Check dtoverlay works with A/B boot setup

[Dave Jones]

Public bug reported:

The dtoverlay command (and dtparam as its alias) both traditionally read
/boot/firmware/overlays/README to determine available overlays and
parameters. The code is also intelligent enough to handle os_prefix
configurations (such as we are switching to in questing), using
/proc/device-tree/chosen/os_prefix. However, does this work if we switch
the directory prefix in question, as when testing new boot assets?

** Affects: raspi-utils (Ubuntu)
