fusebox: define template function to call the fusebox server

Calling the server is a frequent operation. To reduce boilerplate
some [1], define a C++ template for calling server methods.

Move the GetFuseBoxServerMethodCall and the template together, to
connect the idea of 1) getting a server D-BUS method_call, and 2)
calling that D-BUS method_call.

[1] Only hides dbus::ObjectProxy::TIMEOUT_USE_DEFAULT which D-BUS
defines as "infinite". In Chrome / ChromeOS D-BUS implementation,
the default timeout is 30 seconds.
