bug#47717: guix outrageously exhaust itself (freeze) when there is package build failure

[bo0od]

Hi There,

I have used "guix pull" then "guix upgrade" one of the packages couldnt 
be built but thats not the real issue, The real issue it caused guix to 
freeze for like not less than 2+ hours and i couldnt do anything with 
the distro until guix cut out the build/upgradation by itself.
