[virt-tools-list] [libosinfo] Better udev rule installation

[Zeeshan Ali (Khattak)]

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

Provide a configure option to set the udev rule directory. If this
option is not set, udev directory defaults to '$prefix/lib/udev/rules.d'
unless $prefix is '/usr' in which case it defaults to '/lib/udev/rules.d'.
