pm: cpupower: Add missing residency header changes in cpuidle.h to SWIG

"tools/cpupower: display residency value in idle-info" added a new
function to cpuidle.h. This patch adds them to the bindings.

Tested by compiling both libcpupower and the headers; running the test
script that does not use the functions as a basic sanity test.
