From: Leon Romanovsky <leonro@xxxxxxxxxx>
The Virtual Product Data (VPD) attribute is not readable by regular
user without root permissions. Such restriction is not really needed,
as data presented in that VPD is not sensitive at all.
This change aligns the permissions of the VPD attribute to be accessible
for read by all users, while write being restricted to root only.

I added stable@ as it was discovered during our hardware ennoblement
and it is important to be picked by distributions too.
