[unittests] Ignore googletest DWARF directories
[unittests] Ignore googletest DWARF directories

The Swift build system does not generate DWARF symbols in the unittests build
directory. For build systems that do, however, files would be generated with
the test suffix "Tests". These need to be excluded because otherwise
`lit.formats.GoogleTest` tries to execute them.
