[m-rev.] diff: fix div and mod for 32-bit uints in the Java backend

[Julien Fischer]

Fix div and mod for 32-bit uints in the Java backend.

These were broken by commit 9a2c9dc which accidently removed a suffix and
turned a mask constant from a long into an int.

compiler/mlds_to_java_data.m:
      Add the missing suffixes.

Julien.
