[PATCH 3/3] [D] libiberty: Prefix mangled D initializer symbols

This is instead of adding a `.init$' postfix, which gave it a
property-style name.  My rationale being that "initializer for symbol"
is much more informative when inspecting D runtime type information in
gdb, which is the only place where you would encounter references to
this compiler-generated symbol.
