[LTP] [PATCH] alarm02: fix for 32-bit kernels

[Jan Stancek]

Test fails on 32-bit kernels with:
  alarm02.c:55: FAIL: alarm(4294967295) returned 2147483647 as unexpected

because kernel alarm_setitimer() limits seconds to INT_MAX to avoid
negative timeval settings which would cause immediate expiry:

  static unsigned int alarm_setitimer(unsigned int seconds)
  {
        struct itimerval it_new, it_old;

  #if BITS_PER_LONG < 64
        if (seconds > INT_MAX)
                seconds = INT_MAX;
  #endif

Don't test UINT_MAX.
