Closed issue by Chocimier on void-packages repository

https://github.com/void-linux/void-packages/issues/18190

Description:
If template downloads txt file, it is copied into builddir and then not removed, e.g. scons or emacs-ess.

Handling of txt should be changed to copy into wrksrc, or removed, or together with skip_extraction replaced with new variable that hold (distfile, path relative to wrksrc) pairs. Last one would be handy for many cases where XBPS_SRCDISTDIR is accessed currently.

Suggestions?
