Revert "sys_time() speedup"
This basically reverts commit 4e44f3497d41db4c3b9051c61410dee8ae4fb49c, while waiting for it to be re-done more completely. There are cases of people mixing "time()" with higher-resolution time sources, and we need to take the nanosecond offsets into account. Ingo has a patch that does that, but it's still under some discussion. In the meantime, just revert back to the old simple situation of just doing the whole exact timesource calculations. But rather than using do_gettimeofday(), use the internal nanosecond resolution getnstimeofday(), which at least avoids one unnecessary conversion (since we really don't care about whether the fractional seconds are nanoseconds or microseconds - we'll just throw them away).
