Create the (legacy) qemu-kvm link for RISCV as well.
Note that the qemu-system-riscv64 binary, to which the symlink should
point, is in the qemu-extra package. However, if we are on RISCV,
qemu-extra is an hard dependency of qemu. Therefore, it's fine to ship
the link and also set the Provides: and Obsoletes: tag in the qemu
package itself. It'd be more correct to do that in the qemu-extra
package, of course, but this would complicate the spec file and it's not
worth it, considering this is all legacy and should very well go away
soon.
