fontconfig: Re-order configs; Move "fonts.conf" as "50-user.conf"

NOTE:
Explicitly set the orders for Noto CJK fonts (SC, TC, JP, KR), in order
to get rid of "LC_CTYPE" environment variable.
Therefore, the preferred English fonts (e.g., Source Code Pro, Source
Sans Pro) are by default used, avoiding the Chinese fonts being prepend
at the beginning.
