rpm: install to work around build failure on Fedora 41 on arm64

 go1.21 and up have a patch that enforces the use of ld.gold to work around
 a bug in GNU binutils. See;
 - golang/go#22040.
 - golang/go@cd77738

 Fedora 41 and up has a fixed version of binutils, and no longer requires that
 patch, but will fail without ld.gold installed;

Fedora's build of Go carries a patch for that, but it's not (yet) in upstream;

- https://src.fedoraproject.org/rpms/golang/c/a867bd88a656c1d6e91e7b18bab696dc3fcf1e77?branch=rawhide

- As a workaround; install binutils-gold
