fdo#80650 src transl. merge must be case sensitive

This makes the desired changes in
workdir/SrsPartMergeTarget/starmath/source/symbol.src. The only other
merged file that is changed is
workdir/SrsPartMergeTarget/sw/source/ui/misc/numberingtypelistbox.src,
with changes like

                < "1, 2, 3, ..." ; 4/*SVX_NUM_ARABIC
-               < "a, b, c, ..." ; 0/*SVX_NUM_CHARS_UPPER_LETTER   */; > ;
+               < "A, B, C, ..." ; 0/*SVX_NUM_CHARS_UPPER_LETTER   */; > ;
                < "a, b, c, ..." ; 1/*SVX_NUM_CHARS_LOWER_LETTER   */; > ;

This looks okay to me too :-)
