    config: ignore unreadable configuration files
    
    Modified `config_file_open()` so it returns 0 if the config file is
    not readable, which happens on global config files under macOS
    sandboxing (note that for some reason `access(F_OK)` DOES work with
    sandboxing, but it is lying). Without this read check sandboxed
    applications on macOS can not open any repository, because
    `config_file_read()` will return GIT_ERROR when it cannot read the
    global /Users/username/.gitconfig file, and the upper layers will
    just completely abort on GIT_ERROR when attempting to load the
    global config file, so no repositories can be opened.
