[pacman-dev] [PATCH v2] alpm: Fix SIGINT handling re: aborting download

Upon receiving SIGINT a flag is set to abort the (curl) download.
However, since it was never reset/initialized, if a front-end doesn't
actually exit on SIGINT, and later tries any operation that needs to
perform a new download, said download would always get aborted right
away due to the flag not having been reset.
