[PATCH 1/6] tr2: remove NEEDSWORK comment for "non-procfs" implementations

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

I'm fairly sure that there is no way on Linux to inspect the process
tree without using procfs, any tool such as ps(1), top(1) etc. that
shows this sort of information ultimately looks the information up in
procfs.

So let's remove this comment added in 2f732bf15e6 (tr2: log parent
process name, 2021-07-21), it's setting us up for an impossible task.
