The container name is generated once before the retry loop, so
all retry attempts reuse the same name. Move the name generation
inside the loop so each attempt gets a fresh name via the
incrementing counter, consistent with the comment "publish port
ephemeral, allows parallel instances".
Formatting changes (indentation) of lines 208-225 in test/lib/proc_utils.cc
will be fixed in the next commit.

The retry loop in start_docker_service passes the parse callbacks
via std::move into create_handler on each iteration. After the
first iteration, the moved-from std::function objects are empty.
All subsequent retries skip output parsing entirely and
immediately treat the service as successfully started. This
defeats the entire purpose of the retry mechanism.
Fix by passing the callbacks by copy instead of move, so the
original callbacks remain valid across retries.
Fixes SCYLLADB-1542
Previously, the result of when_all was discarded. when_all stores
exceptions in the returned futures rather than throwing, so the outer
catch(in_use&) could never trigger. Now we capture the when_all result
and inspect each future individually to properly detect in_use from
either stream.

Fixes#24998
Helper routine translating input_stream buffers to single lines
did not loop over current buffer state, leading to only the first
line being sent to end listener.
Rewrote to use range iteration instead. Nicer.

Adds a wrapper for seastar::experimental::process, to help
use external process fixtures in unit test. Mainly to share
concepts such as line reading of stdout/err etc, and sync
the shutdown of these. Also adds a small path searcher to
find what you want to run.
