rustc,rustPlatform.buildRustPackage: broaden platforms

rustc supports way more platforms than Linux and Darwin.  We might not
be able to build it for every platform at the moment, but that's what
meta.broken is for.

There are other platforms that rustc can produce binaries for, but
can't run on itself, so those are listed in the defaults for
buildRustPackage.
