A specific version of 5.0, 5.0.28, was pinned in multiversion_setup.sh to enable timeseries_mixed_schema_buckets tests to run in multiversion suites with mixed schema data. Because the platform and architecture for how some of the binaries are reported changed between 4.2 and 4.4, the pinned patch should be moved to the multiversion_platform_44_or_later resmoke invocation.
