[CI] drop the APK disaggregated-proof step

The step located the Android CMake identity by reading CMakeCache.txt next
to each compile_commands.json, but the trace flavor's build also produces
.cxx/tools/<flavor>/<abi>/compile_commands.json copies whose cache lives in
the real per-ABI build dir, so the proof failed on a file-layout assumption
rather than on missing evidence. Remove the step and its artifact upload.
