[aur-general] Delete requests.

[Karol Woźniak]

First: fetcher [1]. It's been superseded by gayeogi for a long time now and
is not even available for download.

Second: (python2-)flakey [2], [3]. They were pyflakes forks meant to be
used by flake8 and I prepared them in advance, but flake8 maintainer
somehow managed to merge those upstream, so we're using pyflakes in the end.

[2]: https://aur.archlinux.org/packages/flakey/
[3]: https://aur.archlinux.org/packages/python2-flakey/
