Improve `diff_data.sh` robustness and performance
There may be added or removed files between two builds, and without this
change the `stat` and `expr $SIZE2 - $SIZE1` calls could fail, leading
to a lot of noise in the output.
Also, the script spent a lot of time incrementing count using `expr`,
which is made faster using arithmetic expressions. On my machine, the
time goes from 24 to 14 seconds.
ICUROOT was unused and thus removed.
