bug#68532: git-crypt can fail after guix gc

I set up a git repo which uses git-crypt a while back, however it seems 
to have broken in the time between then and now.

Looking into how git-crypt seems to handle things; running the initial 
init causes the full path to the git-crypt binary to be written to the 
git config file (.git/config) as a filter.

If one has created a repo using git-crypt, and some time later runs guix 
gc, then the old path to the git-crypt binary likely will be deleted, 
causing git-crypt to break, as it is unable to locate the binary.

One workaround could be running git-crypt in a shell, and registering it 
as a garbage collector root so that the original git-crypt install is 
preserved, but that seems like it would not be an optimal long term fix. 
Updating the config file by hand also seems to fix the issue, though 
that route is similarly a short term fix.
