Fix incorrect argument type in virDomainMigrate3

The 5th argument flags of virDomainMigrate3 is unsigned int, not unsigned long. Therefore, the Java binding should use int instead of NativeLong.

To maintain backward compatibility, the version taking NativeLong as an argument has been deprecated, and a new version taking int has been added.

Although not fully verified, it is likely that no practical issue occurs on supported platforms because:

• On 32-bit platforms, long and int are the same size.
• On 64-bit platforms, the 5th argument is passed via a register.
