[enhancement] better handle bad downloaded source

[mattia-b89]

Pikaur v1.13.2
Pacman v6.0.1 - libalpm v13.0.1 - pyalpm v0.10.6

Description:

Sometimes, downloaded source files are corrupted, thus ckecksum validation fails as well.
When this happens, pikaur, before failing, prompts you a bunch of options:

[R] retry build
[p] PGP check skip
[c] checksums skip
...
[d] delete build dir and try again

This issue can be easily fixed by removing indicated sources. Unfortunately none of the above-mentioned options are able to do it, neither last option since build dir does not contain sources.

Now, I do not know if this is a wanted behaviour or a bug seeing as I have customized SRCDEST variable in /etc/makepkg.conf file.

Anyway, I think it would be a good addition since bad-downloads are quite ordinary issues.

so, it's more of a question if [d] delete build dir and try again should also remove srcs from SRCDEST variable in /etc/makepkg.conf file
