Use clock_settime to implement stime; withdraw stime.

Browse Source 
Unconditionally, on all ports, use clock_settime to implement stime,
not settimeofday or a direct syscall.  Then convert stime into a
compatibility symbol and remove its prototype from time.h.

Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu,
powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.
