Preload libjemalloc.so for long-running Ruby (#16462)
Always mark jemalloc needed if jemalloc is enabled by akihikodaki · Pull Request #4627 · ruby/ruby
https://github.com/ruby/ruby/pull/4627
> Symbols exported by jemalloc is referred by the shared library but not

As a workaround, do not rely on jemalloc enablement of Ruby, and
preload libjemalloc.so instead.
