Update <link> pseudo selector WPTs

In these spec PRs [1][2], the <link> element will no longer match :link,
:visited, or :any-link, and it will no longer navigate the page when
clicked.

This patch also modifies the TestExpectations for one of the modified
tests navigation.sub.html. There was one test case which was
consistently timing out which I removed, which would stop the test from
timing out. However, there are an additional two test cases which time
out when run with run_web_tests.py but pass just fine with
run_wpt_tests.py. In addition, the flags passed to run_web_tests.py on
the trybots make it so that those two test cases which time out get
written to a failure file instead of making the whole test runner time
out, which would count as a failure in TestExpectations. Since the
default flags for run_web_tests.py make it an actual timeout according to
TestExpectations, I left the timeout expectation in there as well.

Hopefully this test can just be run with run_wpt_tests.py in the future
and we can get rid of this TestExpectation.
