Crossdirect: support rust
Install rust in native chroot, if cross compiling and rust is in builddepends. This is needed, so crossdirect works with rust.
Manage the rust cache with pmbootstrap, so downloaded git repositories from cargo are only downloaded once and then kept (speeds up building squeekbox, as it downloads source code for depends at build time currently).
