[build]: Add possibility to override dockerd config file for multiarch builds. (#9325)

- Why I did it
Fixes #8898

Dockerd for multiarch build by default use host OS config file ("/etc/docker/daemon.json").
Default configuration used on host OS may not work for containers run inside sonic-slave.
"DOCKER_CONFIG_FILE_FOR_MULTIARCH" variable allows overriding path to the
config file that will be used for multiarch dockerd.

- How I did it
Added "DOCKER_CONFIG_FILE_FOR_MULTIARCH" to Makefile.work file that allow to
override path to dockerd config file through environment variable:

DOCKER_CONFIG_FILE_FOR_MULTIARCH=${path_to_file}/daemon.json   make ...
If the env variable is not set build the system preserves its default behavior.

- How to verify it
Set DOCKER_CONFIG_FILE_FOR_MULTIARCH env variable
Run build
While build is running execute ps -eo pid,cmd | grep "[0-9] dockerd.*march" command
Verify that --config-file parameter is set to the same path that was specified in DOCKER_CONFIG_FILE_FOR_MULTIARCH variable.
