Grit guesses the `working_dir` for each repo it opens; if it can't find
one Repo#working_dir is nil. This change passes Repo#working_dir to Git
command in Git#native via Git's `--work-tree` command-line option.

Try to ensure that encoding is utf-8

This should resolve the issue of concatenating strings with different encodings which produce the "Encoding::CompatibilityError (incompatible character encodings: UTF-8 and ASCII-8BIT)" error by ensuring that we always attempt to return string with same encoding.

Remove deprecated shell scripting code path

This code lacks the sophistication of Posix::Spawn::Child (there is no
timeout for instance) but it builds the pipeline required for
compressing an archive without resorting to shell scripting and string
interpolation.

This method is not used anywhere in the GitLab code base; we use
Grit::Repo#archive_to_file instead. We are removing #archive_tar_gz
because it is one of the few reasons for keeping an unsafe, deprecated
code path around.
