Bug 20892: use sha256sums-signed-build.txt in download_missing_versions

This fixes the download of the osx64 mar files. Previously we were
unsigning the downloaded mar files and checking them with
sha256sums-unsigned-build.txt. The signed osx64 mar files include files
that are code-signed, so unsigning the mar file is not enough to get a
mar file matching sha256sums-unsigned-build.txt.
