[LTP] [PATCH] times03: don't assume process initial [us]time is 0

times() runs immediately after fork(), but syscall alone
seems to be enough for some systems to already account ticks.

For example on arm64 with 4.14:
  tst_test.c:980: INFO: Timeout per run is 0h 05m 00s
  times03.c:102: PASS: buf1.tms_utime = 0
  times03.c:105: FAIL: buf1.tms_stime = 1
  ...

This patch drops the initial zero check for [us]time.
