Assorted AppImage build fixes
This MR derives from my work in !581 (merged). It fixes locally building AppImages in two ways:
- it allows incremental rebuild of an AppImage by
rsync
ing directories instead of moving them, which is a no-no if there's an existingkrita.appdir
structure in the build root. - it fixes the AppImage packing step, by not setting update information if none is available. This is a case that wasn't checked in Anna's work.
