bug#73751: [cuirass] channel-update-service fails trying to find key with accent in the name

Hi,

This error comes from libgit2, and I suspect the reason is that libgit2
interprets file names according to the current locale and ‘cuirass
register’ is not running in a UTF-8 locale.

Could you check with this patch:

diff --git a/gnu/services/cuirass.scm b/gnu/services/cuirass.scm
