Bug 1440968 - Use a different method for skipping talos tests on windows. r=jmaher

Having both .*-qr/.* and windows.* as patterns in the run-on-projects
test platform list means that a platform like windows10-64-qr matches
both and the parser complains. Instead of doing this, we can remove the
windows patterns and take the talos tests out of the windows-talos
test-set which accomplishes the same thing.
