Do not return an empty path on capitalized self

Path conversion returned an empty path for "Self" due to a hack in
generics Self injection that prevented any "Self!" macro from beeing
recognized correctly.

gcc/rust/ChangeLog:

	* ast/rust-path.cc (Path::convert_to_simple_path): Do not exclude
	capitalized "Self".
