applypatch: Dump patch info on mismatching patching result.

After splitting the previously flaky
ApplyPatchModesTest#PatchModeEmmcTarget tests,
PatchModeEmmcTargetWithMultiplePatches now becomes the sole victim. This
CL dumps additional info to narrow down the cause.

Bug: 67849209
Test: `recovery_component_test` on marlin.
Test: It dumps additional info after using corrupt bonus.file.
