ada: Use CLOCK_MONOTONIC on VxWorks
The monotonic clock keeps track of the time that has elapsed since
system startup; that is, the value returned by clock_gettime() is the
amount of time (in seconds and nanoseconds) that has passed since the
system booted. The monotonic clock cannot be reset. As a result,
time interval measurements made relative to the monotonic clock are
not subject to errors resulting from the clock time being unexpectedly
adjusted between the interval start and end.

* s-oscons-tmplt.c: #define CLOCK_RT_Ada "CLOCK_MONOTONIC" for
__vxworks
