Won't Build on Ubuntu 24

[jmaddington]

This is a fresh, fully upgraded install set up only for building the dattobd package. Running make I get this error:

This matters because it doesn't look like that Datto/Kaseya has released anything for Noble yet:

Only the source code below should be able to be built on Ubuntu24. https://github.com/iamandrii/dattobd/tree/ubuntu-24.04-support

However, there is a problem with fallocate, and if the partition size is large, it will take a long time to take a snapshot. https://github.com/datto/dattobd/issues/392

I have built it so you can use it for testing. Ubuntu24_deb_packages.zip

Hi, we are actively working on official support of Ubuntu 24. Work in progress for now.
