Subject: [bug#50238] [PATCH] build-self: Try printing nicer error messages.

This (reviewed since 5 months, at least the previous versions) patch 
would be helpful for debugging 
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=56836> and many other 
"guix pull: You found a bug" reports.

Greetings,
Maxime.
