cec: fix warnings when building on arm 32 bits

time() returns time_t, whose definition is arch-dependent.
This fixes the following warnings:

	cec-test-power.cpp: In function ‘bool wait_changing_power_status(node*, unsigned int, unsigned int, __u8&, unsigned int&)’:
	cec-test-power.cpp:273:24: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
	  while (time(NULL) - t < long_timeout) {
	         ~~~~~~~~~~~~~~~^~~~~~~~~~~~~~
	cec-test-power.cpp: In function ‘bool poll_stable_power_status(node*, unsigned int, unsigned int, __u8, unsigned int&)’:
	cec-test-power.cpp:301:24: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
	  while (time(NULL) - t < long_timeout) {
		 ~~~~~~~~~~~~~~~^~~~~~~~~~~~~~
