Use git --work-tree when there is a working directory

See merge request !5

The posix-spawn gem's `chdir:` option is not thread-safe.

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.
