Move updatesymlinks to new vpnor feature

The updatesymlinks functionality is to support virtual pnor and it
does not depend on the filesystem type. Move it to a new vpnor
feature so that users can make use of this feature without being
tied to UBI, for example on a eMMC that has a combined BMC+PNOR
image.

Tested: Verified that the witherspoon image contained the new
        script and service file and that it powered on to the host.
