support/dependencies/dependencies.sh: ensure git is >= 2.0.0 for vendoring

The go vendoring fails on CentOS 7 (which uses git 1.8.3.1) with errors
related to shallow clones:

make docker-compose-source
..
go: downloading github.com/matttproud/golang_protobuf_extensions v1.0.4
github.com/docker/compose/v2/pkg/mocks imports
        github.com/theupdateframework/notary/client imports
        github.com/docker/go/canonical/json: github.com/docker/go@v1.5.1-1.0.20160303222718-d30aec9fd63c: invalid pseudo-version: git fetch --unshallow -f origin in /home/jacmet/source/buildroot-mirror/output/host/share/go-path/pkg/mod/cache/vcs/48fbd2dfabec81f4c93170677bfc89087d4bec07a2d08f6ca5ce3d17962677ee: exit status 128:
        fatal: git fetch-pack: expected shallow list
make[1]: *** [/home/jacmet/source/buildroot-mirror/output/build/docker-compose-2.15.1/.stamp_downloaded] Error 1

It works with git 2.0.0 (released May 2014, included in Debian 8), so check
for >= 2.0.0 with logic similar to the GNU patch version check.
