export: Add call to update-desktop-database tool

[luc14n0]

That's important to ensure exported applications will show up in whatever the user/DE is using desktop files for (taskbars, desktop menus, etc) right after exportation.

Desktop Environments should already install update-desktop-database by default - that's how they handle packages installing .desktop files. I'd believe that most Window Managers should also have it.

Thanks @luc14n0

If we add a base dependency we need to add it to the init also

Instead of this, I was thinking we probably want to update the host's desktop-database
So instead of this maybe we can do this:

/usr/bin/distrobox-host-exec --yes update-desktop-database -q 2> /dev/null || :

So this will either force-update the desktop-db on the host, or fail silently if the host doesn't have the tool

Duh, my bad.

Sounds good to me.

Sure thing. Thanks for the amendment.
