First of all, thanks for those changes! Having DTS inside DPDK makes
test synchronization a lot easier. I'm happy to say (unsurprisingly)
that it works with my RISC-V HiFive Unmatched board like a charm.

Though there is a small issue with the lines above. They assume "#" as
the prompt sign, even though original_prompt was set to "[$#>]". This
touches on two problems:
1. # is usually a root prompt - is DTS assumed to be run with root
   privileges? DPDK may (in theory) run without them with some permission
   adjustment (hugetlb, VFIO container, etc.). If we assume DTS needs
   root access, this has to be both documented and validated before
   running the whole suite. Otherwise it'll be hard to debug.
2. Different shells use different prompts on different distros. Hence
   perhaps there should be a regex here (same as with original_prompt)
   and there could be a conf.yaml option to modify it on a per-host
   basis?
