arch_prepareParentAfterFork():204 Couldn't attach to p id=XXXX

Hi

I had build the latest honggfuzz for Android 13 with ndk 22b (the latest tested from documentation) and ndk 25c (the latest at the moment of writing) and in both cases I obtained the same issue:

# ./honggfuzz -i ./input/ -x -- /bin/file ___FILE___
