[bug#71143] [PATCH] services: gitile: Opt out of Git safe dir check.

[guix-patches--- via <guix-patches@gnu.org>]

* gnu/services/version-control.scm (gitile-configuration):
  Add home-directory field for Git configuration file.  It also stores
  Gitile's database, so remove the (now redundant) database field.
* gnu/services/version-control.scm (%gitile-accounts): Move to gitile-accounts.
* gnu/services/version-control.scm (gitile-accounts): Add configurable
  home directory.
* doc/gnu.texi (Gitile Service): Document it.
* gnu/services/version-control.scm (gitile-activation): New function
  creating Git config file for user gitile setting safe.directory
  to * (all directories), so libgit parses directories not owned
  by gitile user in gitile-configuration-repositories.
