Deduplcate rpaths in linkopts

When switching to cpp linking variables, we need to modify the Apple rules to
ensure that -Wl,-rpath,/usr/lib/swift appear before other rpaths.

But we still need to leave behind that rpath in swift rules for linking rules
that don't use apple rules (e.g. cc_binary).

The side effect is that the are now more Appler linker warning about duplicate
rpaths for simple targets.  I don't know of a way to turn that off, and since we
already have logic to deduplicate frameworks, let's deduplicate rpaths while
we're at it.
