Open issues: Update clock_gettime page

The clock_gettime(CLOCK_MONOTONIC) is implemented. See

https://sourceware.org/git?p=glibc.git;a=commit;h=3782ffaf3e6c2a071df029b96712e596b5229838

so this page is out of date.

Rename the page to nanosecond-precision_clock, and remove the
information about clock_gettime(CLOCK_MONOTONIC).

+What about adding a nanosecond-precision clock, too?  --[[tschwinge]]
+
+The y2038 64b interfaces and the mapped time already support it, but the
+granularity is still the clock tick period.

+# Candidate for [[vDSO]] code?
