Add space in name of Rust tuple type

The Rust compiler emits tuple type names with a space after the comma,
like "(i32, f64)".  This changes rust-parse.c to follow.  This isn't
ideal -- probably the DWARF reader should canonicalize these names --
but it is a bit more robust if symbol lookup should change; and anyway
this feature of gdb is probably rarely used.
