Currently, eStargz compression doesn't preserve the original tar metadata
(header bytes and their order). This causes failure of `TestGetRemote` because
an uncompressed blob converted from a gzip blob provides different digset
against the one converted from eStargz blob even if their original tar (computed
by differ) are the same.
This commit solves this issue by fixing eStargz to preserve original tar's
metadata that is modified by eStargz.

The git repo of github.com/containerd/stargz-snapshotter now has two go.mod modules:
- github.com/containerd/stargz-snapshotter
- github.com/containerd/stargz-snapshotter/estargz
So we need to have the following `replace` directive in `go.mod`:
```
github.com/containerd/stargz-snapshotter/estargz => github.com/containerd/stargz-snapshotter/estargz <VERSION>
```
Otherwise `go mod tidy` fails with the following error:
```
go: github.com/containerd/stargz-snapshotter@v0.2.1-0.20201217071531-2b97b583765b requires
github.com/containerd/stargz-snapshotter/estargz@v0.0.0-00010101000000-000000000000: invalid version: unknown revision 000000000000

Current stargz snapshotter pkg doesn't contain registry configuration and the
client of that pkg needs to pass it to that pkg. So this commit includes changes
of propagating buildkitd's registry configuration to stargz snapshotter.
But this is a partial integration of registry logic between buildkitd and stargz
snapshotter because buildkitd's session-based authentication logic is still not
applied to stargz snapshotter. This means private images that require
`~/.docker/config.json` creds can't be lazily pulled yet.
