Update filelock build systems

[utybo]

Hi!

filelock has recently switched to hatchling + hatch-vcs. This PR updates the corresponding override. I've kept setuptools and setuptools-scm in order to keep compatiblity with older versions (not sure if this is the recommended pattern for this).

There is a thing for setting version bounds on build inputs, but inflated build closures are not a big deal imho so this is fine.
If someone wants to implement more specific bounds to get smaller build closures I'll happily merge a follow-up with that.
