Xcode: Fix parallel build depends with universal binaries (#11844)

A post-build phase of each target invokes the XCODE_DEPEND_HELPER.make
file to erase any targets that link to it.  Narrow the set of targets
tested by each post-build phase to those that depend on the newly
completed target.  This avoids removing files from partially built
unrelated targets that happen to be building in parallel.
