Avoid exporting __rust_alloc_error_handler_should_panic more than once.

Exporting `__rust_alloc_error_handler_should_panic` multiple times causes `ld.gold` to balk with: `error: version script assignment of  to symbol __rust_alloc_error_handler_should_panic failed: symbol not defined`

Specifically this breaks builds of 1.70.0 and newer on DragonFly and YoctoProject with `ld.gold`.  Builds with `ld.bfd` and `lld` should be unaffected.
