Print Rust unsized array types a bit more nicely
It's a bit difficult to create an unsized array type in Rust, but if
you do, right now ptype will show something like "[u8; ]". It really
should print "[u8]", though, which is what this patch implements.
This is part of PR 21466.
Built and regtested on x86-64 Fedora 25. I'm checking this in.
