Fixed typo in run_pipeline! function
  -> Open3.pieline to Open3.pipeline

Adjusted run_pipeline! function
  to match rubocop syntax requirements
Adjusted run_pipeline! function
  to use variable instead of string interpolation

Changed run_pipeline! function to have use $ in regex
Changed run_pipeline! function to use Open3.pipeline
instead of Open3.pipeline_start

Changed the run_pipeline! function to instead use Open3.pipeline_start
In doing so, the code is able to grab the last STDERR. In the case
where the error is the one from older tar versions (relating to ./),
it will not raise a Backup::Error. All other instances of command
failure will result in Backup::Error being raised.

GitLab::Sentry has a program_context method to determine whether a

program_context method into GitLab.process_name for more general
consumption.
