[Libosinfo] [libosinfo PATCH 2/3] media: Add installer to the media

[Fabiano Fidêncio]

Having the installer tied to the OS is something that has been shown not
optimal, unfortunately.

An OS may have a few different medias and each media may support a
specific type of script or, even, not support an installer script at
all. With this in mind, let's have the installer scripts tied to the
medias themselves.
