Prior to this commit, an entry in the environment map provided to the
build plugin image building goal or task that had a null value would
result in a failure with a message that was difficult to diagnose.
This commit treats env map entries with a null value as an empty
entry to prevent the failure and also make it easier to provide an
explicit empty entry in the Maven XML.
Fixes gh-22703
