toollib: provide proper hint for referencing VG uuid in case of duplicate VG names

toollib: provide proper hint for referencing VG uuid in case of duplicate VG names

vgrename does not support -S|--select, so do not provide a hint about
using it. Instead, provide a hint about using VG uuid directly.

  WARNING: VG name vg1 is used by VGs DXjcSK-gWfu-5gLh-9Kbg-sG49-dtRr-GqXzGL and MVMfyM-sjOa-M2xV-AT4Y-JddR-h4SP-UO5Ttk.
  Fix duplicate VG names with vgrename uuid, a device filter, or system IDs.
