Updated to (hopefully) not blow up on Travis. Surefire needs
jacoco:prepare-agent to resolve the @{argline}. It's only done in Travis, so
it seems reasonable to just call it directly.
Also makes the surefire version a global and sets it up throughout
(including in some unversioned spots). Makes sure @{argLine} is in the
appropriate <build> tags. It might also be appropriate in reporting tags, but
our management of surefire is pretty variable across the board.
