This patch modifies the old-style hard-coded ignore list. The new-style
text file (in external/webkit/LayoutTests/platform/android) has been
modified separately, as part of the normal WebKit merge process.
Test added in http://trac.webkit.org/changeset/64613
Needs clearAllApplicationCaches() callback. See http://b/issue?id=2944196
