Because of commit e70ea92b "scp: remove
unused macros", which removed the top-level Applications symlink, the
dmg contained an extra dir, e.g.,
LibreOfficeDev_4.1.0.0.alpha0_MacOS_x86/LibreOfficeDev.app instead of
just LibreOfficeDev.app . This symlink used by the installer to
determine the dir to use as top-level for the installation
(solenv/bin/modules/installer/simplepackage.pm:274).

Also revert "Eek, it is hard to get the right path to the .app that is
being built", which was only needed because of the other problem.

This reverts commit 1c25b01f.
