Make rsync() recreate symlinks only on request

Fixing LITE_FOPT_COPYFILE_SYM in copyfile() also changed rsync(), which
has always passed that flag.  Every caller would start getting links in
the destination where they used to get a copy of the file.

Keep following links by default and add LITE_FOPT_RSYNC_LINKS for
callers that want them recreated.
