[fedora-java] EPEL7 Maven macro differences

[Christopher]

One difference I've noticed between maven packaging in EPEL7 and F2X
branches is missing support for the "-r" recursive option in
%pom_remove_plugin (and maybe other tools).

I've seen this "-r" flag used more and more, but it means keeping the EPEL7
branch divergent from the Fedora branches, and that's a bit frustrating.

It's not a huge deal, but it would be convenient if the EPEL7 branch
supported the "-r" flag on these macros.
