Introduce virtual provider uuid (#18322)

libuuid is currently contained in util-linux, libuuid and uuid. This
change introduces a new virtual provider `uuid` and renames the existing
`uuid` package to `ossp-uuid`.

util-linux's libuuid is provided in the form of a separate package
util-linux-uuid to make sure that packages depending on uuid and
util-linux can use a separate uuid implementation, which the concretizer
does not allow if libuuid is contained in util-linux.
