lib: Make igt_while_interruptible() thread-safe
We have the ability to replace the ioctl() call by a wrapper that
performs signal injection (triggering the ioctl to return -EINTR). This
uses a global for handling the signal, which is broken if the test tries
to mixing SIGINT injection and threads. Switch to a thread-local
sigaction.
