#61246 has an alternative solution to this issue. Newer libgit2
versions check for safe.directory configuration entries on user's
global scope. This means that instead of disabling owner validation
in guix code itself, users can exempt directories of their own
choosing. This is IMO a better solution and so the patches provided
here should be disregarded.

However, since libgit2 seems to have changed its API elsewhere after
1.3.x, I've avoided messing with guile-git inputs this time and so
it still depends on libgit2-1.3.

IMO, instead of upgrading libgit2 dependency and risk breaking
guile-git in unknown ways, we should work on revising guile-git's
conformance to latter libgit2 versions (it's currently on 1.5.1).
Meaning not trying to apply the patches Maxime provided, but
working upstream.

WDYT?

Cheers!
