Add more lok debug output.

This should allow as at least to see if soffice_main thread
initialisation gets stuck (which we'd otherwise have a hard time
determining if we are trying to debug e.g. on Android).

Don't use this quick hack on Android.

It *seems* to cause missing areas (at least in Impress).

(i.e. the bottom half or right side of headers on slides can sometimes
 go missing, not using this hack fixes the problem for me).
