It may be useful to create AppVM-specific menu entries in AppVM itself. It may be an application installed there (in /usr/local, or using snap QubesOS/qubes-issues#2766), but it may be also some user custom shortcut. To support this, dom0 will accept menu entries also from TemplateBasedVMs. But to avoid duplicates, qubes.GetAppmenus service should send only menu entries actually stored in that VM, not inherited from its template. To distingush them, first check what type of persistence this VM has (from qubesdb-read /qubes-vm-persistence). If it's rw-only, send only entries stored on /rw. To make it more robust, use $XDG_DATA_DIRS and $XDG_DATA_HOME to discover directories, instead of looking only for /usr/{,local/}share/applications. This makes snap and flatpak handled for free. Fixes QubesOS/qubes-issues#4152
