[PATCH v3 7/7] path.c: remove home_config_paths()

[Paul Tan <pyokagan@gmail.com>]

home_config_paths() combines distinct functionality already implemented
by expand_user_path() and xdg_config_home(), and it also hard-codes the
path ~/.gitconfig, which makes it unsuitable to use for other home
config file paths. Since its use will just add unnecessary complexity to
the code, remove it.
