[LTP] [PATCH] timers: support clockid of CLOCK_REALTIME_COARSE/CLOCK_MONOTONIC_COARSE

[Shi Weihua <shiwh@cn.fujitsu.com>]

mainline commit da15cfdae03351c689736f8d142618592e3cebc3
 (subject: time: Introduce CLOCK_REALTIME_COARSE)
added two clocks (CLOCK_REALTIME_COARSE/CLOCK_MONOTONIC_COARSE) in
2.6.32-rc1, but it has not been responded in ltp. then, the following
error message occured.
-----
clock_gettime03    3  TFAIL  :  failed to produce expected error [expected errno = 22 (Invalid argument), TEST_RETURN = 0]: TEST_ERRNO=???(0): Success
clock_gettime03    4  TFAIL  :  failed to produce expected error [expected errno = 22 (Invalid argument), TEST_RETURN = 0]: TEST_ERRNO=???(0): Success
timer_create04    1  TFAIL  :  didn't fail as expected [expected errno = 22 (Invalid argument)]: TEST_ERRNO=???(95): Operation not supported
timer_create04    2  TFAIL  :  didn't fail as expected [expected errno = 22 (Invalid argument)]: TEST_ERRNO=???(95): Operation not supported
-----

Following patch fixed this bug. and, passed on 2.6.32-rc1, 2.6.33-rc6, 2.6.23.1-42.fc8.
