PR9932: add @cast module search path

Sometimes @cast()ing can fail if the type needed may or may not be
defined in a kernel module.  This patch lets @cast take a colon-
separated list of modules to search for the type definition.

	* tapsets.cxx (dwarf_cast_query): Simplify.  Take the module and
	the code result as reference parameters, and use code.empty() as
	the sign that the type isn't resolved yet.
	(dwarf_cast_expanding_visitor::visit_cast_op): Split e->module by
	colon into substrings, and loop until the type is resolved.
