Remove symbols incompatible with Pacman 5.2

Fixes #73

[jjk-jacky]

Thanks for contributing; However, delta support needs to be completely removed from kalu, and this isn't complete.

Unfortunately I have very little time to spend on this lately, but I've pushed a new branch rm-delta that I think should be good, though it'll need to be reviewed again. Also, I haven't done any sort of testing as well.

Feel free to check it out and let me know if you notice anything wrong/I missed anything.

Cheers,

FYI @jjk-jacky: I've been using the version from the branch rm-delta with no issues. I'm not using all features of kalu: only update checks for the Arch repos and the AUR and the news. I'm not using features like upgrade via UI (I update in the terminal using pacman -Syu).

So my limited tests don't show any issues: thanks for providing the fixes in the branch rm-delta :-).
