Add Inferior.architecture method

Browse source 
I've written a couple of gdb unwinders in Python, and while doing so,
I wanted to find the architecture of the inferior.  (In an unwinder in
particular, one can't use the frame's architecture, because there is
no frame.)

This patch adds Inferior.architecture to allow this.  Normally I think
I would have chosen an attribute and not a method here, but seeing
that Frame.architecture is a method, I chose a method as well, for
consistency.
