Add more POSIX clock type definitions.

kernel/prism implements CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE,
and CLOCK_MONOTONIC_COARSE but the header file does not define them.
We need CLOCK_MONOTONIC_RAW for tlsdate 0.0.13. Add definitions
of the additional clock types which kernel/prism supports.
