[Buildroot] [PATCH] package/python3: require util-linux' <uuid.h>

[Jan Kundrát]

Without this dependency, a top level parallel build fails for me (-j24):

  /home/ci/build/build/host-python3-3.7.2/Modules/_uuidmodule.c: In function 'py_uuid_generate_time_safe':
  /home/ci/build/build/host-python3-3.7.2/Modules/_uuidmodule.c:15:5: error: unknown type name 'uuid_t'; did you mean 'uid_t'?
       uuid_t uuid;
       ^~~~~~
       uid_t
  /home/ci/build/build/host-python3-3.7.2/Modules/_uuidmodule.c:32:5: error: implicit declaration of function 'uuid_generate_time'; did you mean 'py_uuid_generate_time_safe'? [-Werror=implicit-function-declaration]
       uuid_generate_time(uuid);
       ^~~~~~~~~~~~~~~~~~
       py_uuid_generate_time_safe

I *suspect* that this is due to host-uboot-tools which provide
/usr/include/uuid.h and which gets accidentally picked by python3.

There's a bugreport [1] upstream which at leeast appears to be relevant.
