[JENKINS-48795] docker.build fails for Dockerfile which uses ARG in FROM

Dockerfiles are allowed to have ARG directives before the FROM directive, in which case the value for FROM can reference build arguments:

ARG TAG

FROM alpine:$TAG

Using docker.build('foo', '--build-arg TAG=3.7 .') in scripted pipeline on such a Dockerfile fails with:

java.io.IOException: Cannot retrieve .Id from 'docker inspectalpine:$TAG'
