Subject: [PATCH] Fix powertop build with libc++.
<ctime> header is not automatically included with libc++.
Add it explicitly to make powertop build with libc++.
This fixes the following errors:
devices/gpu_rapl_device.cpp:35:14: error: use of undeclared identifier
'time'; did you mean 'tie'?
last_time = time(NULL);
^~~~
devices/gpu_rapl_device.cpp:45:14: error:use of undeclared identifier
'time'; did you mean 'tie'?
last_time = time(NULL);
^~~~
parameters/learn.cpp:161:10: error: use of undeclared identifier
'time'; did you mean 'tie'?
start = time(NULL);
^~~~
