config: Minor --config improvements, fixes (#4034)

Browse source 
* Follow symlink, only file, absolute path for -c

* Create config file only for default paths

* Skip non-file source= glob results

* Check for absolute path on XDG_CONFIG_HOME

As per spec, all non-absolute paths should be ignored.
