[virt-tools-list] [libosinfo 1/5] Use glib-mkenums to register enums with glib

[Zeeshan Ali (Khattak)]

From: "Zeeshan Ali (Khattak)" <zeeshanak at gnome.org>

This commit adds the generation of osinfo_enum_types.[ch] using
glib-mkenums. These files will register the various enums that will get
added to osinfo header files with glib.

Commit message shamelessly stolen from a similar commit to libvirt-glib
by Christophe Fergeau <cfergeau at redhat.com>.
