Move test_fonts into their own directory.

The test fonts have been repackaged into the root of the archive file.
This allows easy extraction with the test fonts being in their own
directory, which is required by GCS.

The alternative would be to add a subdirectory such as fonts, which
would lead to annoying path names such as
//thirdparty/test_fonts/fonts/test_fonts/myfont.tff

The repackaged archive keeps everything as it currently is:
//third_party/test_fonts/test_fonts, which prevents renaming other paths
that depend on this.
