The backup restore code for repositories was assuming that gitlab-shell
is installed in /home/git/gitlab-shell. This commit changes that to use
the configuration setting from gitlab.yml that specifies the path where
gitlab-shell is installed.
- Database name may contain characters which are not shell friendly
- Database password could contain the same
- While we at it there is no harm in escaping generated paths too
- Refactored 2-line system(command)

These fixes will allow a restore of gitlab when the backups and
repositories directories are in non-standard locations (ie sub-dirs
of gitlabhq). Also allows the restore to be run from script
overriding the need of a user to confirm the rebuild of the
authorized_keys file.
