rust: drop bindir/libdir patch

I'm honestly not sure what this patch does since everything appears to
build the same with and without it. I did a `tree` of the sysroots and
images and I don't see any file differences. Something like this used to
be necessary in Gentoo but I dropped it a few releases back.
