Describe the bug
The environment tag of the native-maven-plugin only provides environment variables to the produced binary, but doesn't provide these variables to the image builder.

To Reproduce

Add environment variables to the pom.xml with:

<configuration>
    <environment>
        <variable1>value1</variable1>
        <envVariable2>value2</envVariable2>
    </environment>
</configuration>

then proceed to create an image where System.getenv() is printed/logged in a static initializer. The environment variables provided through the tag are not visible and don't get printed during the image build.

Expected behavior
The environment variables provided through the <environment> tag SHOULD be visible during the image build.
