opal/sys: Correct OPAL_HAVE_SYS_TIMER_GET_CYCLES value

... in the case of `OPAL_GCC_INLINE_ASSEMBLY == 0`

In this case, `OPAL_HAVE_SYS_TIMER_GET_CYCLES` should be 0 because
the `opal_sys_timer_get_cycles` function is not defined.

The history:

1. Before 8d4175ad89, `OPAL_HAVE_SYS_TIMER_GET_CYCLES` was 0.
2. In 8d4175ad89, adf92d6237, adf92d6237, and c62ce1593a,
   `OPAL_HAVE_SYS_TIMER_GET_CYCLES` was changed to 1 by introducing
   `opal/asm/base/*.asm`.
3. In ebce88b7ad, `opal/asm/base/*.asm` were removed.
