Fix template_decl::hash::operator()

While hashing template_decl we inadvertently forget the contribution
of the name of the type to the hash.

This was spotted by Ondrej Oprala.

Fixed thus.

	* src/abg-hash.cc (template_decl::hash::operator()): Combine the
	contribution of the qualified name to the contribution of the type
	name to the hash.
