posix-clocks: Rename the clock_get() callback to clock_get_timespec()

Browse Source 
The upcoming support for time namespaces requires to have access to:

 - The time in a task's time namespace for sys_clock_gettime()
 - The time in the root name space for common_timer_get()

That adds a valid reason to finally implement a separate callback which
returns the time in ktime_t format, rather than in (struct timespec).

Rename the clock_get() callback to clock_get_timespec() as a preparation
for introducing clock_get_ktime().
