Subject: [PATCH] Ignore warnings during appdata generation

The Plasma/PopupApplet service type for example got deprecated and removed,
but is still used by various parts of Plasma 5.8.
This causes kpackagetool to emit warnings, but it still succeeds. However,
this case is handled incorrectly as any stderr output is assumed to be critical
and the file is not installed. As result is 0, no warning message is printed.

This commit fixes this by ignoring the stderr output and using result to indicate
success. Warning messages are printed if applicable.

BUG: 378529
