[virt-tools-list] [virt-viewer] Update shared mime database on install/uninstall

[Christophe Fergeau]

remomte-viewer installs a file to $datadir/share/mime to register a
mime-type for its .vv files. However, after installing this file,
update-mime-database must be run in order to update the shared mime
database. This commit (inspired by what Nautilus/planner are doing) adds
what is needed for that.
If the mime type is not correctly registered, gvfs-info console.vv will not
return the correct mime type, and xdg-open console.vv will fail to start
remote-viewer, and will fall back to running gedit as the .vv file is a
text file.
