Fix a race that could cause us to miss a SIGINT When I refactored the previous commits to unmask SIGINT in owl_global_is_interrupted, I accidentally opened a window for us to miss a SIGINT for a cycle of the event loop if it arrived in owl_select() between a call to that functuon and pselect(). Undo that refactoring to make is_interrupted() just poll the flag, add owl_function_(un)mask_sigint() for convenience, and use them in the relevant locations.
