Make the enforcer plugin work in Eclipse

This eliminates the warning:
"maven-enforcer-plugin (goal "enforce") is ignored by m2e"

And instead, enforcer problems are now visible in Eclipse.

I tried doing it only on runConfiguration and not runIncremental, but
it caused weirdness: the enforcer errors would appear for a couple of
seconds and then disappear again after the incremental compile finished.
Hopefully having it happen on incremental build every time won't cause
too many problems for large projects like fiji.git which take several
seconds to run through the RequireReproducibleBuilds enforcer rule...
