Bug 1541545 [wpt PR 15952] - Consolidate .gitignore files under the root., a=testonly

Automatic update from web-platform-tests
Consolidate .gitignore files under the root (#15952)

Multiple .gitignores aren't supported by the manifest update code when running
against the filesystem, so put all the rules in the root file instead.

This also adds a lint to check for extra .gitignore files.
