controlapi.cpp: try to fix build errors if member 'time' is not found

Ensure backward compatibility for rc_sync and channelEPGformated

- Added conditional compilation in rc_sync to check for input_event_sec macro.
- Used input_event_sec and input_event_usec macros if defined.
- Provided fallback to direct timeval members for older versions.
- Minor formatting adjustment in channelEPGformated for consistency.

This should ensure compatibility with both newer and older
kernel versions, different C library implementations,
and possible standard settings of build systems.
Addressing different definitions of the input_event structure maintains
robustness across kernel, library, and build system configurations.
