configure: do not create legacy symlinks

With more than three years since Meson was introduced in the build system, people
have had quite some time to move away from the foo-softmmu/qemu-system-* and
foo-linux-user/qemu-* symbolic links.  Remove them, and with them another
instance of the "softmmu" name for system emulators.
