Bug#908591: maven-debian-helper: Ignored rules are included in the installed poms like publish rules

[Emmanuel Bourg]

Package: maven-debian-helper
Version: 2.3.2
Severity: serious

I introduced a regression in maven-debian-helper/2.3 when I modified
the Maven mojos to use the plugin annotation. A copy/paste error in
SysInstallMojo caused the ignore rules to be added to the installed
poms instead of the publish rules. This caused plugin resolution
issues like #908542.
