time-util: fall back to CLOCK_MONOTONIC if CLOCK_BOOTTIME unsupported
It was added in 2.6.39, and causes an assertion to fail when running in mock hosted on 2.6.23-based RHEL-6: Assertion 'clock_gettime(map_clock_id(clock_id), &ts) == 0' failed at systemd/src/basic/time-util.c:70, function now(). Aborting.
