Tests: Remove explicit no-signing marks from BundleTest

These were added by commit e29a92f525 (Xcode: Make BundleTests
compatible with Xcode 11, 2019-09-01, v3.16.0-rc1~158^2).  The
real problem is that the `.app` is constructed with text files
under the `.app/Contents/MacOS/` folder.  Move those, and drop
the special no-signing configuration.
