Duplicate about_memory.html to create a Linux version.
This is in preparation for adding about:memory support for Linux, but the change is otherwise too large to be considered the same file without this trick. git-svn-id: svn://svn.chromium.org/chrome/trunk/src@24750 0039d316-1c4b-4281-b951-d872f2087c98
