Catch canceled step and mark build has failure

[hashar]

When using the Parameterized plugin, the triggered job can be canceled. That causes an AbortException to be thrown. Since it is not handled, PostBuildScript let it through and the build is marked in failure even when one explicitly asks to ignore any error.

Catch AbortException and mark the build has being in failure in such a case instead of bubbling up the exception.

I am in the process of writing a test to cover this and will update the PR once I have finished.

Thanks for the contribution, @hashar ! Sorry, that I didn't react earlier. I somehow must have overseen it.
