rustc_resolve: fix instability in lib.rmeta contents

Browse source 
rust-lang/rust@23032f31c9 accidentally introduced some nondeterminism
in the ordering of lib.rmeta files, which we caught in our bazel-based
builds only recently due to being further behind than normal. In my
testing, this fixes the issue.
