e2e tests: sigproxy: fix rare hang condition

The sig-proxy test creates a FIFO, runs podman with actions
that write to it, then tries reading from the FIFO.

Opening a FIFO for read or write blocks until the other end is
opened for the corresponding write/read. If our podman process
fails for any reason, the test's FIFO open will hang forever.

Solution: open with O_NONBLOCK.
