[PATCH] ext: fix documentation for C ext-defined classes

[Eric Wong <e@80x24.org>]

Defining the "Raindrops" class explicitly helps RDoc find
subclasses for documentation, and ought to reduce the binary
size slightly due to the removal of rb_intern calls.

Furthermore, use "Socket" to ensure the base class for
Raindrops::InetDiagSocket is documented properly in RDoc.
