Move json symlink before populating dbus interfaces

This commit reorders the flow of ibm-read-vpd app execution by
first allowing the app to create symbolink link to the respective json
and then populate dbus interfaces by having the right json.

Without this change, only those motherboard subfrus which are present
in the default inventory json will gets its interfaces populated during
genesis boot. Thus leaving machine specific motherboard's subfru's
(powersupply, pcieslots, etc.,) dbus interfaces unpopulated.

With this change, all of the motherboard subfrus which are present in
the symlink json will get its interfaces populated on dbus during
genesis boot.

Test:
Tested on simics rainier2s2u. Able to see all of the interfaces of
motherboard's
subfrus after the genesis boot.

1. motherboard's subfru - powersupply0
