[PATCH 5/5] fetch: Improve tar pipeline unpack commands

When originally implemented, tar didn't support many of the compression options so
it was easier for the code to use pipelines. tar does support these now, so we
can switch to using them.

zstd isn't converted since the --zstd option isn't present in tar v1.30 present
on RHEL 8 derived distros.
