Revert "Makefile: added deps on bundle dir"

This still causes the bundle rebuild. Under normal circumstances it
won't matter but as we sign the directory after creating the bundle
and before creating dmg, it actually hurts, becasue to the DMG goes the
freshly-created (unsigned) bundle.

This reverts commit 7294347.
