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.
