Change rpc_py to use rpc_cmd function.
The former needs to be defined explicitly in the scripts
that uses function, while the latter is a function
already available in autotest_common.sh.
Additionally delete unnecessary rpc_py declarations
and override rpc_cmd where additional arguments are
needed (like -s sock_name.sock).
