moby: docker 19.03-RC3: cp broken with debian containers (arm?)

Description

docker cp is broken with Debian containers (on armhf).

Steps to reproduce the issue:

1. install the latest docker 19.03 on armhf
2. docker run --name foo -d debian:buster-slim sleep 1000
3. docker cp foo:/root/.profile .

Describe the results you received:

Error response from daemon: error processing tar file: docker-tar: relocation error: /lib/arm-linux-gnueabihf/libnss_files.so.2: symbol __libc_readline_unlocked, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference : exit status 127

Describe the results you expected:

Work.

Additional information you deem important (e.g. issue happens only occasionally):

This works fine with:

• Alpine (musl)
• BusyBox

This also works fine with Debian on D4M using 19.03-RC2

Either this is limited to armhf, or this is only in RC3 and not in RC2.
