Fix syslogger to not fail when log_rotation_age exceeds 2^31 milliseconds.
We need to avoid calling WaitLatch with timeouts exceeding INT_MAX. Fortunately a simple clamp will do the trick, since no harm is done if the wait times out before it's really time to rotate the log file. Per bug #7670 (probably bug #7545 is the same thing, too). In passing, fix bogus definition of log_rotation_age's maximum value in guc.c --- it was numerically right, but only because MINS_PER_HOUR and SECS_PER_MINUTE have the same value. Back-patch to 9.2. Before that, syslogger wasn't using WaitLatch.
