patch 9.0.1601: filetype detection fails for *.conf file without comments

Browse Source 
Problem:    Filetype detection fails for *.conf file without comments.
            (Dmitrii Tcyganok)
Solution:   Use "conf" filetype as a fallback for an empty .conf file.
            (closes #12487, closes #12483)
