lib: Avoid assertion if sig_ioctl is unsed from a child accidentally

The timer is tied to the creator thread, i.e. it is not inheritable
across fork() or clone()/pthread_create(). Using it thus causes an
assertion failure in the test after the one that aborts (and so on until
we perform an interruptible test correctly) - one mistake snowballs. We
can stop the snowball by doing an initial check and diverting back to
drmIoctl().
