Subject: [PATCH] bridge: Fix `set_function_prototype` tool with recent axiom
 versions

Update the parameter name because recent axiom versions (v1.13.5+)
intentionally filter out `prototype`. This is the only use of the
parameter `prototype`. `signature` is already accepted as alternative
by the Binary Ninja side.

Closes #75.
