lang/rust-nightly: Update to 1.58.0.20211030
Make the no-hardlinks-patches conditional and move them to
files/no-hardlinks.
Newer kernels should return sane kern.proc.pathname values for
hardlinks which will hopefully help avoid the intermittent "can't
find crate for `std`" build failures we had on the package
builders.
Thanks to kib@ for fixing kernel behavior. Now let's see if it
makes a difference for lang/rust-nightly.
