python3: use pure python UUID backend
Python3 at runtime identifies the uuid backend to use to implement safe
time-based UUID generation functions. When the python _uuid extension
module, /usr/lib/python3.7/lib-dynload/_uuid.cpython-37m-<arch>.so
is not found, the fall back is to use a pure python implementation.
- If uuid.h from util-linux is available at build time, the _uuid
module is built and used. A Buildroot patch allows us to disable this
build-time check and never build the _uuid module.
With the bump to python 3.7, an optional dependency on util-linux was
added to build the _uuid module. However, this may lead to circular
dependencies. To break this circular dependency, we can disable the
build of the _uuid module and always use the pure python implementation.
