[PATCH 3/4] fetch2/repo: Make fetcher always sync on unpack

[Oleksandr Andrushchenko <andr2000@gmail.com>]

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>

Currently if repo has fetched the repository and
cached it to a tar file it never runs repo sync again,
thus making the build use potentially outdated repo.
Fix this by implementing unpack functionality which runs
repo sync.
