Create ThirdPartyModuleListComponentInstaller.

This creates a component installer for the third party module list
component. It also creates a corresponding ModuleListManager in
chrome/browser/conflicts for caching where the most recent module
list is stored on disk. This is necessary so that the module list
will be available to chrome_elf and sandbox code.
