release-macos: Remove the explicit call to strip-llvm.sh

Since e56fb975e9, strip-llvm.sh
has been called as part of build-all.sh.

This avoid stripping out files that have been installed into the
share directory by later stages in build-all.sh. (strip-llvm.sh
currently flat out removes the share directory.)
