Clock_gettime, settime and getres implementations are unncessarily complex due to using defines and C file inclusion. Simplify the code by replacing the redundant defines and removing the inclusion, making it much easier to understand. No functional changes. * sysdeps/posix/clock_getres.c (__clock_getres): Cleanup. * sysdeps/unix/clock_gettime.c (__clock_gettime): Cleanup. * sysdeps/unix/clock_settime.c (__clock_settime): Cleanup. * sysdeps/unix/sysv/linux/clock_getres.c (__clock_getres): Cleanup. * sysdeps/unix/sysv/linux/clock_gettime.c (__clock_gettime): Cleanup. * sysdeps/unix/sysv/linux/clock_settime.c (__clock_settime): Cleanup.
