Cherry Zhang 19a932ceb8 cmd/link: don't mark shared library symbols reachable unconditionally 
During the transitioning period, we mark symbols from Go shared
libraries reachable unconditionally. That might be useful when
there was still a large portion of the linker using sym.Symbols,
and only reachable symbols were converted to sym.Symbols. Marking
them reachable brings them to the dynamic symbol table, even if
they are not needed, increased the binary size unexpectedly.

That time has passed. Now we largely operate on loader symbols,
and it is not needed to mark them reachable anymore.

Fixes #40416.
