Deploy DTBs and other image artifacts into subdirs to avoid conflicts

[Zhihang Wei <wzh@ilbers.de>]

Image task "do_copy_boot_files" deploys kernel, initrd, and device tree
binaries to the deploy directory.

When different images for the same target (e.g., "-base" and "-debug")
are built in parallel, DTB deployment may fail because DTBs do not
contain image-specific components in their filenames, unlike the kernel
and initrd. As a result, artifacts from different builds may be written
to the same location.

Here we deploy the DTBs and other image artifacts to subdirectories,
with names of distro image encoded to the path.

Note that this results in separate copies of the same artifacts being
deployed for each image build.
