Summary REGRESSION(312588@main) [WPE][CMake] clang build broken with new hmap support...

The header map generated by `generate-header-map` contains keys only for header basenames (e.g. `wpe-platform.h`), missing any subdirectory-prefixed form (e.g. `wpe/wpe-platform.h`). While this works fine for WebKit's own headers, this assumption breaks when headers are expected to be included from nested directories. For example, GLib public API headers are usually included as `<wpe/wpe-platform.h>`. So the header map should be able to resolve it the same way `-I .../WPEPlatform` would.
