[wpt] Fix missing testdriver(-vendor).js in webusb/
https://web-platform-tests.org/writing-tests/testdriver.html#markup
says:
The testdriver.js and testdriver-vendor.js must both be included ...
in the top-level test document when using testdriver from a different
context
This is needed to make the test portable to non-content shell browsers,
which implement testdriver.js with WebDriver and cross-context
message events, not with internal JS bindings.
