[boost] [swap] unbreak tests

I've checked in the below. The libs/utility/swap/Jamfile.v2 has the
same content present twice (complete with copyright notices). This is
not good, because if you ask Boost.Build to built two targets with the
same name, the same set of sources, and otherwise identical, Boost.Build
asks "wazzup?".

I suspect this duplicate content is a consequence of how the "patch" program
handles file addition, but anyway, it's nice idea to actually run library's
test before touching the library.
