record: don't dereference symlinks while copying over stat data
Previously, we could be calling os.utime or os.chflags (via shutil.copystat) on
a symlink. These functions dereference symlinks, so this would have caused the
timestamp of the target to be set. On a read-only or similarly weird
filesystem, this might cause an exception to be raised.
This is pretty hard to test because conjuring up a read-only filesystem for
test purposes is non-trivial.
