[osinfo PATCH] Mark the PrimaryVolumeDescriptor struct as packed

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

This tells gcc it shouldn't add some padding between the struct
members. which is important because we rely on this structure size
being exactly 2048. One of its members is guint8 ignored2[246]; (only
a 2 byte multiple) so all the fields of the struct won't be aligned
on a 8 byte boundary, so gcc could do some unexpected things on
some arch.
