Implement missing miner functions on FreeBSD

cryptonote::miner::get_system_times(): Fetch the system's total and
idle time using sysctl kern.cp_time.

cryptonote::miner::get_process_time(): Use the same implementation as
Linux and OSX, the times(3) function conforms to POSIX.1 and is
available on FreeBSD.

cryptonote::miner::on_battery_power(): Try to fetch the battery status
using sysctl hw.acpi.acline. If that fails (if ACPI is not enabled on
the system), then try querying /dev/apm.
