[Libguestfs] [PATCH V2 2/2] JAVA: fix the type of optargs_bitmask

[Wanlong Gao]

If we don't add a "L" at the end of a number, its type will be
int but not long.

This bug is found when compiling JAVA binding with the following error:

./com/redhat/et/libguestfs/GuestFS.java:14731: error: integer number too large: 2147483648
      _optargs_bitmask |= 2147483648;
                          ^
