blaze config: include "fragment -> [fragment options] map".

This is necessary to link options to the fragment(s) that contain them.

For example, if two configurations have a different --linkopt value, this belongs to the CppOptions FragmentOptions, which is included with the CppConfiguration fragment.

Serves https://github.com/bazelbuild/bazel/issues/10613.
