[settings] Display canonical setting name in output of "show" command

Browse Source 
Enable the "show" command to display the full, canonicalised name of
the fetched setting.  For example:

  iPXE> show mac
  net0/mac:hex = 52:54:00:12:34:56

  iPXE> dhcp && show ip
  DHCP (net0 52:54:00:12:34:56)... ok
  net0.dhcp/ip:ipv4 = 10.0.0.168

  iPXE> show net0/6
  net0.dhcp/dns:ipv4 = 10.0.0.6
