gnu: python-flit-scm: Improve package.

Reduce closure size by removing redundant python-setuptools and
python-wheel as it was a workaround import issue which was resolved by
using flit_core.buildapi directly.

* gnu/packages/python-build.scm (python-flit-scm): Fix indentation.
  [arguments] <build-backend>: Let it auto detect.
  <phases>: Add 'fix-backend.
  [native-inputs]: Remove python-setuptools and python-wheel.
