libalpm: handle syscall interruption correctly
It is possible to throw EINTR from a system call such as open(), close(), or waitpid() if custom signal handlers are set up and they are not initialized with the SA_RESTART flag. This was noticed by Andreas Radke when ^C (SIGINT) was given during the call to waitpid(), causing it to throw the EINTR error and we could not accommodate it. Simply wrap these calls in a simple loop that allows us to retry the call if interrupted. Signed-off-by: Dan McGee <dan@archlinux.org>
