rustc: Always handle exported symbols on the wasm target

Currently when linking an artifact rustc will only conditionally call
the `Linker::export_symbols` function, but this causes issues on some
targets, like WebAssembly, where it means that executable outputs will
not have the same symbols exported that cdylib outputs have. This commit
sinks the conditional call to `export_symbols` inside the various
implementations of the function that still need it, and otherwise the
wasm linker is configured to always pass through symbol visibility
lists.
