Description

When running linux container with a LCOW support enabled on a windows healthchecks fail. It seams that CMD command incorrectly picks up cmd.exe over sh/bash for linux OS.

Steps to reproduce the issue:

1. docker run --name=test -d -e "ZOOKEEPER_SYNC_LIMIT=2" -e "ZOOKEEPER_TICK_TIME=2000" -e "ZOO_MAX_CLIENT_CNXNS=3000" -e "ZOOKEEPER_CLIENT_PORT=2181" -e "ZOOKEEPER_SERVER_ID=1" --platform
   =linux --health-cmd="echo 'ruok' | nc -w 2 -q 2 localhost 2181 | grep 'imok'" confluentinc/cp-zookeeper:3.2.4
2. docker inspect --format "{{json .State.Health }}" <containerId>
