Move internal/private dependencies to Requires.private

Program using the xcb sub-modules has indirect compile and runtime
dependency of core xcb. To ensure this out we currently list xcb in
the Requires field of the pkg-config files. While this provides all
the required dependencies for successful compilation this causes
over-linking and hides potential linking miss-use against the xcb modules.

By moving to Requires.private we retain the compilation and runtime
compatibility and avoids any runtime problems.
