Won't work; the home directory is probably user-writable, so the user
can just delete the symlink.  Remember, if you have write on a directory
you can create or delete files in that directory (even if you don't own
them, if sticky bit isn't set on the directory).  I suspect you'd need to 
have ~/.xscreensaver be an actual copy of the file and set it immutable 
with chattr +i to make this approach work.
