Recently util-linux gained an (optional) build dependency on libcryptsetup.
But libcryptsetup build-depends on util-linux for blkid (optional, can be disabled)
and uuid (mandatory).
Split out util-linux-uuid in a different recipe to break the cycle.

v1: util-linux 2.35 is not out yet, but I'd like to get the preparatory work
    underway as I'm not sure if this is the best approach or if there are
    alternatives. Suggestions and comments very welcome. Thanks!
v2: changed packages names to reflect old ones (eg: libuuid1 -> util-linux-libuuid)
    and leave uuid build enable in main recipe to allow for uuidgen build to happen,
    as it does not have its own autoconf switch. Delete the library manualy from
    the main recipe after build instead, and add dependency.
    Might help to break loop python3 -> util-linux -> libselinux -> python3, as it's
    only libuuid that is needed, see https://lists.yoctoproject.org/g/yocto/message/47570
v3: rebased and refactored to have a common util-linux.inc file
v4: added RDEPENDS on util-linux-libuuid on various packages to fix QA warnings
v5: remove RDEPENDS and instead have util-linux RDEPEND on util-linux-uuid.
    Removed PACKAGES_remove and instead filter out libuuid via the package generation
    regex.
    Rebased on util-linux 2.36.2.

With this patch, there is a very weird failure on the autobuilders, two
a-full builds failed with this:

This also happens with glibc-2.33-r0:


ERROR: glibc-2.33-r0 do_package: Error executing a python function in exec_python_func() autogenerated:

Not sure this helps but we also get:

WARNING: nativesdk-util-linux-2.36.2-r0 do_package_qa: QA Issue: nativesdk-util-linux rdepends on nativesdk-util-linux-uuid, but it isn't a build dependency? [build-deps]
