rG689663d4654f: Initialize CLOCK_UPTIME for itmer events
Summary

Since we move to implement Linux's CLOCK_MONOTONIC with CLOCK_UPTIME, we
broke the some timer support for Linux. Fix this by initializing
CLOCK_UPTIME as a posix clock so we can use in that context.

You might consider EXTERROR-ise kern_ktimer_create(), there are too many EINVALs there. Specific diagnostic would be useful.
