sys-file-writer: Write variable names in mrsets in lowercase.

SPSS appears to write the short names of the variables in a
multiple response set in lowercase, so this commit make PSPP
do the same.

Thanks to Curt Reinhold <Curt.Reinhold@psychonomics.de> for
providing the .sav file that led to this discovery.
