Subject: [PATCH] rust: don't select CONSTRUCTORS

This was originally part of commit 4b9a68f2e59a0 ("rust: add support for
static synchronisation primitives") from the old Rust branch, which used
module constructors to initialize globals containing various
synchronisation primitives with pin-init. That commit has never been
upstreamed, but the `select CONSTRUCTORS` statement ended up being
included in the patch that initially added Rust support to the Linux
Kernel.

We are not using module constructors, so let's remove the select.

 	  Enables Rust support in the kernel.

 	  This allows other Rust-related options, like drivers written in Rust,
 	  to be selected.

 	  It is also required to be able to load external kernel modules
 	  written in Rust.

 	  See Documentation/rust/ for more information.

 	  If unsure, say N.
